Keannas,BOB2

In this scribe we had to Show some examples of answers that were wrong.
-Like What was your mistakes.-How will you remember what to do in future tests.


My mistake was not reading the question correctly and also not studying alot.
-To inprove this I will study ,and read the questions more than once in order to get it.



1. In a group of 84 students surveyed, the ratio of students preference is seven oatmeal eaters to four granola eaters to three toasted 0 eaters.

-of 84 students, how many prefer oatmeal ?

-Of 84 students, how many prefer granola ?

-What percent ( to one decimal place ) of the group prefers toasted 0's ?




2. A rapid transit has 17 passengers on it as it starts to run. At the first stop 3 passengers get off and 37 passengers get on. What is the ratio of the number of passengers who were on the train as it arrived in the station to the number who were on the train when it left the station?Express your answer in the lowest terms?

Noelle's BOB2 ratio

Hello Everybody,

One question that i got wrong with the test, was question number 4.

The question is :
Four students are runninh for student council president. Of 30 Students polled, 15 chose Mike, 3 chose Patricia, 6 chose Brian, and the rest chose karen. what is the ratio of votes for girls to votes for boys in the student council election? express the ratio in lowest terms.

The answer was choice a, but i chose b.
The reason i got that wrong was because i switched the ratio. The correct answer was 3:7 and I chose 7:3.



The next question was:
Question number 5

Eric is able to stop 85% of the shots on goal. If he faces 27 shots on goal, how many goals would likely be scored on him?

The correct answer was option b which was 4, but the answer i put was option c which was 9.

What were the mistakes you made on your test. Show examples of answers that were wrong. What was your mistake. How will you remember what to do in future tests.


What I learned and what I need to work on

I really need to work on is to study more about ratios tables, where you make a ratio table. and read the questions more carefully , so I could come up with a really good answer.

1. In a group of 84 students surveyed, the ratio of students preference is seven oatmeal eaters to four granola eaters to three toasted 0 eaters.

Of 84 students, how many prefer oatmeal ?

Of 84 students, how many prefer granola ?

What percent ( to one decimal place ) of the group prefers toasted 0's ?

Thank you for reading my post and please leave a comment!

Part 2 (BOB2)

What were the mistakes you made on your test. Show examples of answers that were wrong. What was your mistake. How will you remember what to do in future tests.

• Some of the mistakes I did was not reading the questions carefully. Some of the questions I got wrong were because I didn't do the math, and I was such in a hurry. Next time I do a math test, or any test, I will study, and take my time to read the questions carefully, and solve them properly using word ratios, ratio tables, etc.

Rewrite 2 questions that gave you difficulty with different numbers.

1. Use the data in the table below to determine which sports teams have equivalent scored by to scored against ratios.

A survey of students in the school found that 18 had Sony phones, 56 had Motorola cell phones, 12 had LG phones, and 26 had Nokia phones.

• What is the ratio for Motorola phones to the total of phones? Simplify your answer.

a. 56:112 b. 7:14 c. 28:56 d.1:2

Darlene's BOB & RATIO for Oct. 20

Today in class we did a lot of work that had to to with part-to-part ratios, part-to-total ratios and part-to-part-to-part ratios . Then Mr. Harbeck assigned us to make a scribe post about it.

Part to Part Ratios

• Green to Blue = 6:1
• Blue to Yellow = 1:4
• Red to Green = 6:6

Part to Total Ratios

• Green to Total = 6:17
• Blue to Total = 1:17

Three Part Ratios

• Yellow to Green to Blue = 4:6:1
• Red to Yellow to Green = 6:4:6

Ratio, Fraction, Decimal and Percent

• Blue to Yellow = 1:4, 1/4, 0.25 & 25%

Equivalent Ratios

• Red to Green = 6:6

Simplification :

• Red to Green = 3:3

Red : 6 divided by 2 = 3
Green : 6 divided by 2 = 3

The three questions !

1. What would the ratio be for Green, Yellow to Total ?
2. What would the ratio be for Yellow, Red, Blue, Green to total ?
3. How would you write Green to Total in fraction, decimal and percent ?

Part 2

Mr. Harbeck told us to re Bob our Bob post and talk about our mistakes on our test.

The mistakes I made on my test was not expressing the ratio in lowest terms and reading the question wrong even though the important things I needed to know was already highlighted.

Ex.

The ratio of the red cards to the whole deck is :

• I put in 2:4 instead of 1:2. I forgot to express the answer in the lowest terms.

I will remember to express the ratio in lowest terms by reading the highlighted words carefully next time.

2 questions that you had difficulty with

Q. 17)

Team Scored by Scored Against
Baseball Team A 10 8
Basketball Team A 115 92
Hockey Team A 6 4

Q. 4)

Four students are running for student council president. Of 60 students polled, 30 chose Mike, 6 chose Patricia, 12 chose Brian, and the rest chose Karen. What is the ratio of votes for girls to votes for boys in the student council election? Express the ratio in lowest terms.

Part to Part Ratios

- Part to Part ratios compare 2 different groups of things from the same total.

Blue to Yellow

2:6

Green to Red
6:10

Yellow to Green
6:6

Part to Total Ratios
-Part to Total ratios compare one group of things to the total amount of all of it.

Red to Total

Part to Part to Part ratios
-Part to Part to Part ratios compare 3 different groups from the same total to eachother.

Yellow to Red to Green
6:10:6

Red to Blue to Yellow
10:2:6


Choose a ratio to do in a Ratio form, Percent, Fraction, and Decimal.

Yellow to Red

6:10

Yellow/Red = 6/10

6/10= 0.6

0.6 x 100 = 60.0%


Make an Equivalent Ratio

I am going to use the one I just used.
Yellow to Red
6:10 = 3:5

6/2 = 3
10/2 = 5


Three Questions for you to do.
1) What is the Red to Total in an equivalent ratio?

2) Make a Part to Part to Part ordering the colours of M&M's from least to greatest.

3) How many Part to Part ratios could you make if there were two more colours there?



This is my BOB scribepost.
Please comment.





BOB Continued

I made mistakes by not looking my work over and by not going back to questions that I didn't get.
I can fix that on future tests by going back to do the hard questions later and reading the questions very slowly.

Warren stopped 90% of all the shots. There were 30 shots attempted. How many shots made it in?
A picture frame has a Width to Length ratio of 6:8. If the Width of the photo is 10 what is the Length?

Bob Part 2

Some mistakes I made on the test were:
- I didn't read the question carefully
- I didn't show my work based on ratios
- I didn't simplify some of the answers

What I need to do for the next test is:
- Read the question at least 2 times
- Make sure I put the answer in the lowest term

Questions that gave me difficulty were:

6. A stable has 39 horses available for trail rides. Of these horses, 26 are all born, 8 were mainly white, and the rest are black. Express in lowest terms the ratio of brown horses to mainly white horses to black horses.
a) 13 : 4 : 2 b) 13 : 4 : 5 c) 26 : 8 : 5 d) 39 : 26 : 8

8. A picture frame has a width to length ratio of 5 : 7. If the width of the photo is 9 cm, the length of the photo is
a) 11 cm b) 12.6 cm c) 14 cm d) 16 cm

Answer these questions in the comment box.

bob 2

My mistakes in my test were some of the multiple choice and the ordering ratio at the back of the test .

for example :
number 5 . Eric is able to stop 85% of the shots on goal. If he faces 27 shots on goal, how many goals would likely be scored to him ?
a. 3 b. 4 c. 9 d. 15

for that question i put , C . when the right answer was D .

One question that gave me difficulty was number 15 . Ordering the ratios from lowest terms.
Another is question 17 , About the teams with the scored by and scored against fact .

Ralph and BOB Ratio October 20 2009

Today in class we did alot of work with dealing with ratios. Our homework today was to do a post that had:

3 part to part ratios, 2 part to total ratios and 2 three part ratios

Then I had to:

write that ratio in ratio notation, fraction, decimal and percent form.

Next I would have to:

pick one and show how to create equivalent ratios.

Finally create 3 questions that you want people to answer in the comments. Do not make them to hard or too easy.

Part to Part Ratios
Green to Blue=7:1
Red to Green=6:7
Red to Yellow=6:4

Part to Total Ratios
Red to Total=6:18
Blue to Total=1:18

Three Part Ratios
Red to Blue to Yellow=6:1:4
Red to Blue to Green=6:1:7

Converting Ratio to a : Fraction, Decimal, and Percent

Red to Total : 6:18 or 6/18 or 0.33 (Infinite) or 33.33(infinite) %

Simplifying Ratios

6:18 simplified would be 1/3

6 (divided) by 6 is 1

18 (divided) by 6 is 3

6:18 = 1/3 = 0.33(infinite)

THE 3 QUESTIONS!!!

1. Express the ratio Yellow to Red in a Ratio, Fraction, Decimal, and Percent.

2. What would the ratio be if the Yellow to Red ratio if the ratio was simplified.

3. What would be the ratio of Red, Green, Blue, Yellow: Total

Thanks for Reading!

Don't Forget to Comment!

ANSWER MY QUESTIONS!

Some mistakes I made on my test were that:

1)I didn't read the questions well enough.

One question was about votes for student council.

The part I didn't read well enough was that the ratio had to be GIRLS to BOYS .

The ratio I put was boys to girls so I got the question wrong.

2)I should find more easier and faster ways to solve harder equations.

For question 17 I had to find out what two teams were equivalent.

I spent alot of time looking for a number that I could multiply the two numbers by, when I could have,

divide the first number by the second number and see which ones match.

3)I need to always go over the test again in case I missed a question.

I could of gotten more marks if I read over all the questions. Question number 16 was a really easy question but I accidentally skipped it and went onto the next question.

QUESTIONS

1. A picture frame has a width to length ratio of 10:14. If the width of the photo is 18 cm , the length of the photo is _______

a) 22 b)25.2 c)28 d) 32

2. A stable has 78 horses. Of these horses, 52 are brown, 16 are white and the rest are black. Express the ratio in the lowest terms of brown to white to black horses.

a) 26:4:5 b)13:4:2 c) 52:16:10 d) 26:8:5

Don't forget to comment, and answer my questions please.

---------------------

PART 2

1. What were the mistakes you made on your test. Show examples of answers that were wrong. What was your mistake? How will you remember what to do in future tests?
One mistake I made on my test was forgetting to simplify a ratio in LOWEST terms. Some of the examples of the answers were :
8:32 in simplified form would be 1:4, but some wrong answers would be 4:16 or 2:8.
10:80 in simplified form would be 1:8, but a wrong answer would be 5:40.
5:125 in simplified form would be 1:25, but a wrong answer would be 2:6.
18:27 in simplified form would be 2:3, but a wrong answer would be 6:9.
What I should do in future tests to remember how to simplify a number is, I can just think about the lowest possible way for a ratio, like splitting a number in half or dividing with larger numbers.

2. Rewrite 2 questions that gave you difficulty with different numbers. Answer the questions correctly in the comments to your blog. Encourage others to participate at your blog by getting them to answer your questions.

2 QUESTIONS.

a) Eric is able to stop 50% of the shots on goal. If he faces 16 shots on goal, how many goals would likely be scored on him.

b) A picture frame has a width to length ratio of 10:14. If the width of the photo is 18 cm, the length of the photo is ...

DON'T FORGET TO COMMENT AND ANSWER MY QUESTIONS :)

BOB,Ratio for October 20, 2009

The picture I chose was the "Crayon Line Up".

Part to Part Ratios:

Shades of green to purple = 3:1
Gold to shades of blue = 1:3
Shades of pink to silver = 2:1

Part to Whole Ratios:

Shades of blue to total = 3:12
Purple to total = 1:12
Shades of pink to total = 2:12

Three Part Ratios:

Gold to shades of green to silver = 1:3:1
Shades of pink to shades of blue to orange = 2:3:1
Purple to gold to shades of green = 1:1:3

Converting the ratio to a fraction, decimal, percent:

Shades of green to total = 3:12 = 3/12 = 0.25 = 25 %
Tip: to get the percent, multiply the decimal by 100 and to get the decimal you divided the numerator by the denominator.

Simplifying the Ratio:

Shades of green : total = 3:12 = 1:4 (simplified) or shades of green/total = 3/12 = 1/4 (simplified)
* To simplify the ratio, I divided 3 by 3 to get 1 and I then divided 12 by 3 to get 4 so my simplified ratio is 1:4 or 1/4.

Questions:

What would the new ratio be of the shades of pink to total crayons if it was simplified?

Express the shades of pink to silver crayons as a fraction, decimal, and percent.

If the amount of each color was doubled what would be the new ratio of the shades of blue to shades of pink and what would be your new total of crayons?


-------------------------------------------------------------------------------------------------

BOB: Part 2

The mistakes I made on my test were:

• I didn't put some of my answers in lowest terms
• I didn't read the questions carefully
• I didn't show how I got my answer using ratio related strategies (ratio tables)

One of the questions I got wrong was:

3. A normal deck of playing cards has 52 cards in four suits (club, diamonds, hearts, and spades) of 13 cards each. Two of the suits are black and two suits are red. The ratio of red cards to the whole deck is

a) 1:1 b) 1:2 c) 2:3 d) 2:4

My answer for this question was letter d) 2:4.The correct answer was b) 1:2. I got this question wrong because I didn't put my answer in lowest terms.

What I need to do for my next test is:

• read the questions carefully
• show my work using ratio tables, etc.
• highlight the keywords in the questions (word ratio)
• use effective strategies to answer the questions
  

Two questions that gave me difficulty were:

7. A rapid transit train has 39 passengers on it as it starts its run. At the first stop 12 passengers get off and 18 passengers get on. What is the ratio of the number of passengers who were on the train as it arrived in the first station to the number who were on the train when it left the first station? Express your answer in lowest terms.

a) 2:3 b) 13:15 c) 18:12 d) 27:39

8. A picture frame has a width to length ratio of 5:7. If the width of the photo is 9cm, the length of the photo is

a) 11cm b) 12.6cm c) 14cm d) 16cm

Please answer these two questions in the comment section.

April's BOB and Ratio for Oct.20,2009.

For homework, Mr.Harbeck told us to choose a picture and make ratios with it. I chose this picture.

3 PART TO PART RATIOS:

YELLOW TO ORANGE: 2:2 GREEN TO BROWN: 1:2 SILVER TO BLACK: 1:1

2 PART TO WHOLE RATIOS:

GREEN TO TOTAL: 1:22 PINK TO TOTAL: 1:22

2 THREE PART RATIOS: YELLOW TO ORANGE TO BROWN: 2:2:2 SILVER TO BLACK TO GREEN 1:1:1

THE RATIO I HAVE CHOSEN TO REPRESENT IS YELLOW TO ORANGE.

YELLOW TO ORANGE:
2:2

FRACTION:
2/2

DECIMAL:
1.00

PERCENT:
100%

HOW TO MAKE EQUIVALENT FRACTIONS:

Equivalent fractions are just equal fractions. So to
make an equivalent fractions, whatever you do to one side, you just have to do to the other side. It's that simple!


For example, this picture shows the number of orange crayons, to the number of total crayons. So to get an equivalent fraction, I just divided both the orange and total by 2. You may also divide the two different numbers if you like.


HERE ARE MY 3 QUESTIONS:

1)What is the difference of part to part ratio and part to whole ratio ?

2)How can you simplify 16/28?

3)What is the ratio for white to total pencil crayons?

WELL, THAT'S MY SCRIBEPOST FOR THE DAY. THANKS FOR LOOKING. AND PLEASE COMMENT. :)

*DON'T FORGET TO STUDY FOR THE MATH TEST TOMORROW!*

-----------------------------------------------------------

BOB CONTINUED.

MISTAKES:
Most of my mistakes were from not understanding the questions properly. Or I didn't take enough time to get the best answer. (simplifying).

Here are some examples:

3) A normal deck of playing cards has 52 cards in four suits (clubs, diamonds, hearts, and spades) of 13 cards each. Two of the suits are black and two of the suits are red. The ratio of red cards to the whole deck is:

a)1:1 b)1:2 c)2:3 d)2:4

The correct answer is b, 1:2. But instead of b, I picked d. 2:4. I know that 1:2 and 2:4 are the same thing, but it needed to be simplified.

Here are some question that gave me some difficulty to answer.

In a group of 84 students surveyed, the ratio of student preference is seven oatmeal eaters to four granola eaters to three toasted O eaters.
12. Of the 84 students, how many prefer oatmeal?
13. Of the 84 students, how many prefer granola?
14. What percent (to one decimal place) of group prefers toasted O's?

17. Use the data in the table below to determine which sports teams have equivalent scored by to scored against ratios.

BOB and Ratio

Today in math class Mr.Harbeck assigned us to do a BOB. We had to pick 3 part to part ratios, 2 part to total ratios and 2 three part ratios.

Part to Part Ratio (P:P):

blue to yellow- 1:4

yellow to green- 4:6

red to blue- 6:1





Part to Total (P:T):

blue to total- 1:17

red to total- 6:17

Part to Part to Part Ratio (P:P:P):

blue to yellow to green- 1:4:6

yellow to total to red- 4:17:6

My ratio that I will be expressing in a fraction, decimal, and percent is 1:4

fraction: b/y = 1/4

decimal: 0.25

percent: 25%

The equivalent fraction for 1:4 is

1:4 = 2:8
you get that by multiplying 2 from 1:4.

My questions are:

1. What is the ratio of green to M?

2. What is the ratio of red,blue,yellow to total?

3. Wat is the ratio of purple to green?
(what makes up purple)


THANKS FOR READING! (don't forget to answer the questions)

1What were the mistakes you made on your test. Show examples of answers that were wrong. What was your mistake. How will you remember what to do in future tests.

The mistakes that I made was not expressing the ratio in lowest terms, forgetting to put a word ratio and not using the ratio table.

The next time I do a test I will read the questions more carefully, study for the test, and to have a ratio table put in.

Rewrite 2 questions that gave you difficulty with different numbers.

1.Use the data below to determine which sports teams have equivalent scored by to scored ratios.

2. A picture frame has a width to length ratio of 10:12. If the width of the photo is 14, the length of the photo is

My BOB on Ratios

Part to Part Ratios
- Part to Part ratios are ratios that compare 2 parts of a group to each other

Blue to Red
9 : 7

Green to Blue
2 : 9

Red to Green
7 : 2



Part to Total Ratios
- Part to Total ratios are ratios that compare a part of a group to the total amount

Green to Total
2 : 18

Red to Total
7 : 18



Part to Part to Part Ratios
- Part to Part to Part ratios are ratios that compare 3 different parts of a group to each other

Green to Red to Blue
2 : 7 : 9

Red to Blue to Green
7 : 9 : 2



Choose a ratio to write in Ratio Notation, Fraction, Decimal, and Percent Form.

Word Ratio Red to Total
Ratio Notation 7 : 18
Fraction Form Red/Total = 7/18
Decimal Form 7/18 = 0.3888.....
Percent 0.3888... x 100 = 38.88%


Choose a ratio to show Equivalent Ratios.

Green to Total
2 : 18

Equivalent ratios display the same data. You could get them by dividing the ratio by a common factor or by multiplying it by the same number.




Three Questions for you to Answer

1) Write the ratio of Red, Blue to Total in 3 different ways.

2)Write Blue to Green as a percent, decimal, and fraction.

3)Find and write all the Part to Total ratios and then simplify them.

Part 2

For our part 2 BOB we are supposed to put what we did wrong on the test but what we could improve on. I think I could improve on finding out an easier way to find the answer to a question without taking up so much time.

Binesi's BOB & Ratio

Part to Part Ratios

Green to Blue=6:1

Yellow to Green=4:6

Red to Blue=6:1

Part to Total Ratios

Green to Total=6:17

Blue to Total=1:17

Three Part Ratios

Green to Blue to Yellow=6:1:4

Blue to Red to Green=1:6:6

Questions:

Write an fraction for 8:3, then create 3 equivalent fractions for it.

Write a decimal for 6:17, then convert this to a percent.

Write simplified versions for 10:30, 49:70. Then turn them both into decimals, then into percents.

BOB Part 2

Here is the answer to one of the many question I got wrong:

17.Use the data in the table below to determine which sports teams have equivalent scored by to scored against ratios.

Baseball Team A- Scored by:10 Scored against:8

Basketball Team A- Scored by:115 Scored against:92

Hockey Team A- Scored by:6 Scored against:4

You need to turn the scores into ratios, then into decimals. I didn't turn them into decimals, which is why I got 0 as my mark for that question.

When you turn them all into decimals you get baseball-1.25, basketball team-1.25, and hockey-1.5.

So the equivalent scores are baseball and basketball.

I will remember how to do this type of question for a future test because, I will know that 2 answers will be equal.

Two Questions that gave me difficulty are. . .

8. A picture frame has a width to length ratio of 10:14. If the width of the photo is 18cm, then the length of the photo is. .

a. 39.1cm b. 29.7cm c. 25.2cm d. 19cm

The width of the frame is 18cm while the length is unknown.To get this we must see what we multiplied by to get from 10 to 14.

When we multiply 1.4 by 10 we get 14, so if we multiply 18 by 1.4, what do we get?

6. A stable has 50 horses available for trail rides. Of these horses, 25 are all brown, 20 are mainly white, and the rest are black. Express in lowest terms the ratio of brown horses to mainly white horses to black horses.

a. 25:20:5 b. 5:4:1 c. 10:8:10 d. 50:25:20

What was your answer and why?
