### Finding Hypotenuse...

Here is my work showing how to get the hypotenuse

The portion for this problem is..
a² + b² = c²
6² + 10² = c²
(6x6)+(10x10)=c
²
36 + 100 = c
²
136 = c
²
136 = √c²
136 = 11.66

The length of the hypotenuse also labeled as h is 11.66cm

### Allysa's 2 Minutes to Make a Difference Reflection.

1. - Make a Difference Brainstorming Powerpoint.

- 2 Minutes to Make a Difference VERSION 1

- 2 Minutes to Make Difference FINAL CUT

3. How did you find your expert? List 3 important points your expert added to your movie. What did you learn from your expert? We found our expert from the help of Mrs. Armstrong. She recommended people from the Red Cross, the Philippine Canadian Centre of Manitoba, etc. We learned a lot from our expert, one thing is that the people in poverty aren't necessarily victims, but survivors. Another thing is that the Philippines is a country that experiences strong natural disasters from time to time. Lastly, we learned that here in Canada, we have a strong network of agencies to help us. But in the Philippines, they suffer from conflicts, low income levels, and such.

4. If you did not find an expert tell us why you were unsuccessful. Be honest. We were successful in finding our expert.

5. What was your greatest success in the 2 minutes project. What skills will you take away with you and use in the future? Our greatest success was the fact that we found an expert to talk to about our topic. A skill I may take with me is laying everything out before starting anything, just so we don't have to memorize and cram everything in when we're actually doing it.

6. What frustrated you during the movie making process? What strategies did you use to become successful? What frustrated us the most was probably some of the teamwork and finding an expert. We never actually thought we'd find an expert in our short period of time left, luckily Mrs. Armstrong (The lady judging our videos) helped us brainstorm a bunch of places to find one. For the teamwork part, we just all started working harder and became more focus when there wasn't as much time left to finish our video.

7. Why is the 2 Minutes project important to Grade 8 Students? The 2 minutes project is important to us grade 8's because, we learned how to care and help out other people other than ourselves and the others around us. Also because other people in the world needed the help more.

8. How will you make a difference in the future? In the future, we decided to pack up a box and send it to the Philippines to give to the people who need it. Some things we could pack in the box are clothes, canned or processed food, and even money.

### 2 Minutes to Make a Difference Final Reflection

Copy 1

FINAL VERSION

Reflection :

I changed the video effect because the final version one grabs peoples attention more.
The student comments were helpful and I took a look at them all and it did make my movie better than it was before. Our group did not find an Expert because we did Racism and Racism doesn't really have experts but my group and I did look on the internet to see if we could get an expert but we couldn't..
The skills I learned while editing and making this movie are helpful and now I can use Windows Movie Maker if I ever need to make a movie again. While editing this movie I really got to understand Windows Movie Maker better than I did before.
By putting pictures and Audio of us speaking during the pictures in the movie was very difficult but then we helped each other and got it together.
We made this video to show people that they can put a stop to racism because it hurts and it also gets better sick .. I think its important to make a difference in grade 8 because were getting older and we are old enough to understand whats respectful or not.
If everyone stops being racist towards each other racism will stop ! It just takes one person to make a difference.

Part 1

A) Video

B) Textbook Pg 202, Question 6

Fraction: 3x3/8
C) Textbook Pg 208, Question 4

Fraction: 1/4/2
D) Textbook Pg 208, Question 7

A pitcher of orange juice is 2/3 full. If 4 students equally share the juice, what fraction of the full pitcher does each student get?
Part 2

E) Fraction x Fraction

Fraction: 2/3 x 5/6
F) Fraction x Mixed Number

Fraction: 1 1/5 x 2/5

Turn the mixed fraction into an improper fraction by multiplying the whole number and the denominator, then add the numerator. Use that as a new numerator and use the same denominator from the mixed number. Then you multiply the numerators and denominators to get the answer.
G) Mixed Number x Mixed Number

Fraction: 2 3/4 x 2 3/4

Turn both mixed numbers into an improper fraction by multiplying the whole number and the denominator, then add the numerator. Use that as a new numerator and use the same denominator from the mixed number. Then you multiply the numerators and denominators, and convert the improper answer back to a mixed number.

The pictures are dark because the lights were off in my room and I was too lazy to turn the lights on. Sorry ^_^

Part 3

Division

Fraction: 1 1/2 / 3/4

Turn the mixed fraction into an improper fraction by multiplying the denominator and the whole number together and then add the numerator. Use the answer as a new numerator and use the old denominator. Replace the mixed fraction with the improper fraction and start the division. For the first way, you can cross multiply by multiplying the numerator of one fraction together with the other denominator from the other fraction and you do the same with the other denominator and numerator. Then you can just simplify the answer into lowest terms.
Fraction: 3/4 / 1/2

Part two:

How to multiply a fraction and a fractions
I will use question number 2 on the fraction quiz as an example.
First step; multiply the two numerators

Second step; multiply the two denominators.

The answer for the first step is going to be the new numerator and the answer for the second step is the new denominater. Now the fraction is 10/18, what you have to do now is simplify, that would be the third step if it is possible to simplify. So the final answer would be 5/9.

How to multiply a fraction and a mixed number
For an example, i'll be using question 4.
First step; Convert the mixed fraction. (multiply 8 & 4 then add 7.) = 39/8 (keep the denominator)

Second Step; multplpy the two fractions (improper [39/8] and proper [1/7]) = 39/56

third step; convert if needed. - i didn't convert this one so i only got 1/2 a mark for this question.

How to multiply a mixed fraction with another mixed
This question is number 8, i'll be using this as an example.

First step; convert both mixed fractions to a fraction (= 11/4 & 11/4)

Second step; multiply them both (= 121/16)

Third step; simplify (= 7 9/16)

### Gilberts Fractions Growing Post

In the past couple of classes we've been learning how to multiply and divide fraction so here's a post for how to do it.

Multiplication

OK so there are two ways to find the answer one way is to use a diagram. As you see in my picture I have showned you how to do that. The second is the easier way all you have to do is multiply the both denominators and numerators to get the answer.

DivisionOK so to divide a fraction you have to draw a diagram. After you have done that you you split it into 1/2 then shade in 1 after that you split it into four horizontally and shade in 1. Then you get 1/8.

Word Problem

Iqaluit has frost on about 3/4 of the days in a year. It has frost on five times as many days as Vancouver. On what fraction of the days of the year does Vancouver have frost?

To get theis answer all you have to do is the follow the steps I wrote on division.

Part 2

Fraction x Fraction

To do Fraction x Fraction all you have to do is multiply both the denominator and numerator to get the answer.

Mixed number x A Fraction

OK so all you have to do is make the mixed fraction into a fraction to do that you have to multiply the whole number by the denominator then add the numerator. After you have done that you have to fractions then you just multiply both the denominator and numerator to get the answer.

Mixed Number x Mixed Number

OK to multiply a mixed number by a mixed number is very simple. All you have to do is convert both mixed numbers into fractions then you multiply both fraction to get the answer. After that you simplify your answer then divide it to get your final answer.

### Connor's Fraction Growing Post

Part 1

A) Video of my Quiz
(No Video)
Question 1
Determine 3 x 5/18, in lowest terms.
A. 5/6 B. 5/9 C. 5/18 D. 5/54

3 x 5 = 15
1 x 18= 18

15/18 in lowest terms is 5/6

B) Multiplying Fractions

I will use question 6 to explain how you can multiply fractions.

1) One way is to use 4 pictures of 1/2

1/2
1/2
1/2
1/2

1/2 + 1/2 + 1/2 + 1/2= 2/2 2/2

2 or 4/2

2) The Second way to do it is to use a number line

Just draw a horizontal line and label is 0, 1, 2 then keep adding the halves together.

C) Dividing Fractions

I used question 5 from the text book to help me explain how to divide fractions.

One way you can show you divided a fraction is by using a fraction strip. Then you divide the strip into even smaller pieces then take the half the original amount of strips.

Another way you can divide a fraction is by multiplying the denominator of the fraction by the divisor.

4/8 divided by 2 = 4/16
8x2

D) Word Problems

7. A pitcher of orange juice is 2/3 full. If four students equally share the juice, what fraction of the full pitcher does each student get?

To solve word problems, you have to find what it is asking. For example, in this question it is asking you to divide the pitcher of orange juice between 4 students. Then you set up a simple sentence answer. Next, you solve the problem. Lastly, you fill in the sentence.

Each student will get 2/12 or 1/6 of the pitcher.

I need to find what 2/3 divided by 4 will equal.

2/3 divided by 4 = ?

PART 2
Fraction x Fraction

How I solved it:
Multiply 1 by 2 and you will get 2 (numerator)
Multiply 5 by 7 and it's 35 (denominator)
the answer is 2/35 (try to convert it as small as possible)

Mixed Number x Fraction

Step 1: Multiply the whole number by 6 and it equals 6..... Then add the 5 to the 6 and you will get 11...
so its 11/6

Step 2:
Multiply 11/6 with 3/10 and you will get 33/60.

Step 3: Simplify it....
divide it by 3

Mixed Number x Mixed Number

How I got it:

Step 1: Multiply 5 by 12 and then add 2 so you will get 62/12
Step 2: Multiply 4 by 23 and add 6 and you will get 92/23
Step 3: multiply 62/12 by 92/23 and you will get 5704/276
Step 4: Then divide it.... 276 will go to 5704 20 times and there will be 184 remaining. So its (20) 184/276
Step 5: Simplify
I simplified it by 4 and i got (20) 46/69

So the answer is (20) 46/69

COMMENT!!!!

### Jenn's Fraction Growing Post !

Over the Past Few weeks we have been learning about dividing and multiplying fractions ! Here is my growing post .

a)I recorded a video, but I couldn't find it ;(

b) Using one question from questions 6 or 7 on page 202 of the textbook, explain two ways to multiply a fraction by a whole number. You should use pictures to help explain. -

the question i chose was 4 x 1/2 !
one way you could do this equation is to draw 4 groups of 1/2 to get the answer of 4/2 or 2.

another way you could do the equation is 4/1 x 1/2 . You multiply the 2 numerators first and then you multiply the two denominators .

c) Using one question from questions 4 or 5 on page 208 of the textbook, explain how to divide a fraction by a whole number. You should use pictures.

To divide a fraction, you cut it into how many rows the whole number is. Since the fraction is one half, you can shade in one half of the whole. After that, since the fraction is still one half, it means you can have one fourth of the shaded section. That concludes to the answer being one eighth.

d)A pitcher of orange juice is 2/3 full. If four students equally share the juice, what fraction of the full pitcher does each student get?

The Answer ? Each student gets 2/12 or 1/6 of the full pitcher of orange juice.
2/3 divided by 4 = 2/12 or 1/6 (simplify )

Part two .

Fraction x Fraction

To do Fraction x Fraction you simply multiply the denominator and numerator to get the answer.

Mixed number x A Fraction

first off you , make the mixed fraction into a fraction to do that you have to multiply the whole number by the denominator then add the numerator. After you have done that , you have to do the fraction, then you just multiply both the denominator and numerator to get the answer.

Mixed Number x Mixed Number

To multiply a mixed number by a mixed number is suprisignly very simple. All you must do is convert both of the mixed numbers into fractions then you multiply both fractions to get the answer. After that, you must simplify your answer then divide it to get your final answer. (:

PART 2

How to Multiply a Fraction by a Fraction
The first step to multiply a fraction by a fraction is to multiply the first fraction's numerator with the second fraction's numerator. Next, you have to multiply the first fraction's denominator with the second fraction's denominator. Finally, to get your answer, you take the answers from the numerator multiplied by the other numerator question and the denominator multiplied by the other denominator and make a fraction of the answers (Simplify if possible).

How to Multiply a Fraction by a Mixed Fraction
The first thing I did to multiply a fraction by a mixed number is to convert the mixed number to an improper fraction by multiplying the whole number by the denominator. Then you take that answer and add te numerator. Next you make that answer a fraction by just taking the denominator and adding the last answer on top of it. After that you multiply the numerator with the improper numerator and multiply the denominator with the improper fraction's denominator. Finally, you convert the improper fraction into a mixed fraction by counting how many times the denominator fits into numerator and make the remainder into a fraction(Simplify the fraction if possible).

How to Multiply a Mixed Fraction by a Mixed Fraction
The first step you're supposed to do when you are multiplying a mixed fraction with a mixed fraction is to make both of the mixed fractions into improper fractions. Then you multiply the numerators and the denominators. Next, you get the answer's numerator and denominator and you find out how many times the denominator fits into the numerator. After that, you make the remainder into a fraction (Simplify if possible). That is how you multiply two mixed fractions.

b) Multiplying Fractions

From the text book, I will use question 6 a) to explain how you can multiply fractions.

There are many ways to show what the product of 4 x 1/2 is. But the equation is basically telling you to add up 1/2, 4 times. Here is one way:

Another way to show multiplication is using a number line :

One last way is to multiply the numerators and the denominators:

c) Dividing Fractions

I used question 5 a) from the text book to help me explain how to divide fractions.

One way you can show you divided a fraction is by u
sing a fraction strip. First you show your fraction on the strip and then you divide the strip by the divisor:

Another way you can divide a fraction is by multiplying the denominator of the fraction by the divisor:

d) Word Problems

Here, I'll show you how to solve a word problem using a question from the text book.

7. A pitcher of orange juice is 2/3 full. If four students equally share the juice, what fraction of the full pitcher does each student get?

To solve word problems, you have to find what it is asking. For example, in this question it is asking you to divide the pitcher of orange juice between 4 students. Then you set up a simple sentence answer. Next, you solve the problem. Lastly, you fill in the sentence.

Part 2

1) Fraction x Fraction

When you multiply a proper fraction by another proper fraction, you follow two steps. First, multiply the numerators my each other and then the denomi
nators. The second step you do after multiplying, is that you put the fraction in lowest terms if it is not already.

2) Mixed Number x Fraction

To find the product of a mixed number and a fraction, you have to follow a few steps. The first step is to convert the mixed number into an improper fraction by multiplying the whole by the denominator and the adding the numerator. After you get the improper fraction, you multiply the numerators and denominators. If your answer is an improper fraction, you convert it back to a mixed number by dividing the numerator by the denominator then put in it lowest terms. But if your answer is a proper fraction, you just convert it to lowest terms.

3) Mixed Number x Mixed Number

The steps to find the answer of a multiplication question using mixed numbers is that first, you have to turn the mixed numbers into improper fractions. Then, you multiply the numerators and denominators. After that, you turn that improper fraction back into a mixed number. Finally, you put it into lowest terms.

Part 3

In today's class, we learned how to divide fractions. We came up with three different ways to find them. But for me, I'm more comfortable with using only two of the ways so those will be the two I will explain.

a) Dividing Proper Fractions

When you divide a proper fraction, one way you can do it is by using cross multiplication. You get the denominator by multiplying the denominator of the dividend and the numerator of the divisor. To get the numerator, you multiply the numerator of the dividend by the denominator of the divisor. If it is an improper fraction, convert it into a mixed fraction then put it into lowest terms.

The second way to get the answer is by finding a common denominator. When you get the common denominators. The numerator of the dividend it the numerator of the quotient and numerator of the divisor is the denominator for the quotient. And again if it is an improper fraction, turn it into a mixed number then convert it into lowest terms.

b) Dividing a Mixed Number and a Proper Fraction
Here, I'll explain two ways to find the quotient of a mixed number and a proper fraction.

The first way you can find the quotient is by cross multiplying. First, you convert the mixed number into a improper fraction. Then you multiply the numerator of the dividend the denominator of the divisor to the numerator of the quotient. Next, you multiply the denominator of the dividend and the numerator of the divisor to get the denominator of the quotient. After that, if it's an improper fraction convert it into a mixed number. Lastly, put it into lowest terms.

The second way you can find the answer is by using a common factor. The first thing you do is to convert any mixed numbers into an improper fraction. Next, you find a common factor. After you convert the fractions so they have a common factor, you will easily find the quotient. The numerator of the quotient is the same as the numerator of the dividend and the denominator of the quotient is the same as the numerator of the divisor. After that, you turn the improper fraction into a mixed number. Lastly, you put it into lowest terms.
