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.

Question 3

Fraction growing post April.11

1.) 3/1 x 1/8 = 3/8

2.) 1 1/5 x 2/5 = 6/5 x 2/5 = 12/25

3.) 2 1/2 x 1 3/4 = 5/2 x 7/4 = 35/8

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

My answer was A.

Show your work.

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

Then add them together

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

Your answer would be
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














How I got the answer:
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
The answer would be 11/20





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.

Ammorn's Fraction Growing Post

In a few of the classes, we learned how to multiply and divide fractions.

A) I still didn't get to record my quiz.

B) 4 multiplied by 1/2

C)1/4 divided by 2

D) 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?

2/3 divided by 4

PART 2

3/4 x 7/8

1 1/5 x 2/5

First I converted the mixed fraction into an improper fraction to make it easier to multiply. To convert it, I multipled the denominator by the whole number and then I added the numerator. So the improper fraction would be 6/5.

So then I change the equation to 6/5 x 2/5. After, I multiply the numerators together and the Denominators together. The answer is 12/25.

2 3/5 x 3 4/5

For this question, I have to convert the mixed fractions into improper fractions like I did in the above question. So the new equation is, 13/5 x 19/5. Then multiple the numerators together and the denominators together. The answer is 182/25, but the simplified answer is 7 22/25

Larrisa's Fraction Growing Post

Part 1


a) Here is a video of how I got my answers to my fraction quiz.

It shows you how to multiply and divide fractions with whole numbers.







b) Explain two ways to multiply a fraction by a whole number.

Here is an example of two ways to multiply a fraction by a whole number.

I chose the question 4 x 1/2 .
- The first way you could do is draw 4 groups of 1/2 to get the answer of 4/2 or 2.










- The second way you could do is 4/1 x 1/2 . You multiply the 2 numerators and then you multiply the two denominators. If you don't get it , here is a picture :


c) Explain how to divide a fraction by a whole number.

Here is an example of how to divide a fraction by a whole number.

I chose the question 1/2 divided by 4.

- To divide a fraction by a whole number you have to draw the fraction which is 1/2 and shade in 1/2 of it and then you divide it by the whole number which is 4 , when you divide it you have to divide it in a horizontal line. If your confused , here is a picture :



















d) Pick a word problem.

Word Problem : 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 ?

For a word problem you need to read the question and find the key words then highlight them . While your doing a word problem, you need a simple sentence.
Key Words : Pitcher of orange juice 2/3 full. Four students What fraction of the full pitcher does each student get ?


















Simple Sentence : Each student gets 1/6 of the full pitcher. How I got the answer : First find the multiple of 4 in the denominator that is 3 which equals to 12 then multiple 2 by 4 which equals to 8, then divide 8 into4 because there is 4 students, your answer will be 2/12 = 1/6.

THANKS FOR READING MY POST (:

IF I HAVE ANY MISTAKES PLEASE COMMENT (:


Part 2

a) Here is a picture of how to multiply a fraction by a fraction.
How I got the answer : I multiplied the 2 numerators and the 2 denominators. If you don't get it here is a picture below :













b) Here is a picture of how to multiply a fraction by a mixed number.
How I got the answer : I multiplied the whole number by the denominator to get 5 then I added the numerator so it equals to 6 then I kept the fraction the same and multiply the them together to get 12/25.













c) Here's a picture of how to multiply a mixed number by a mixed number.
How I got the answer : I multiplied the whole with the denominator which equals to 10 then I added the 3 to get 13. Same with the other side. Then I times those 2 to get 247/25. After I had to divide it because 247 is to large. I can't explain it... so here's the picture :












IF I MADE ANY MISTAKES PLEASE COMMENT !


Part 3

a) How to divide : You divide the first fraction which is 3/4 so you draw a fraction strip and divide it by 4 and color in 3, because of 3/4. Then you divide it by 1/2 going horizontal. then you color in 1 because of 1/2. If your confused here's a picture.

Brayden's Fraction Growing Post

This video shows how I got the answers to my Fraction Quiz.
















Now I'm going to explain two ways to multiply a fraction by a whole number.

One way would be drawing 4 groups of 1/2



Another way would be to multiply the two numerators.



Now I'm going to explain how to divide a fraction by a whole number.

My example is 1/4 ÷ 2.

Use your fraction strip and divide it into fourths. Then color in 1/4 of it. Next you divide your fraction strip in half as seen in the picture.




Next we have to answer a word problem.

12) It takes 4/5 of a roll of ribbon to wrap six packages. What fraction of a roll does it take to wrap three packages?

It would take 2/5 of a roll to wrap three packages.

I found that out because if 4/5 of a roll of ribbon wraps six packages you can just divide 4/5 by 2 and get 2/5 which would wrap three packages.

----------------------------------------------------------------------------
Part 2

Fraction x Fraction

Fraction x mixed number

4/5 x 1 1/2

First you have to convert the mixed number to a improper fraction.

1 x 2 = 2
2 + 1 = 3
= 3/2

Then you multiply the two fractions.

4/5 x 3/2 = 12/10 or 6/5 or 1 1/5

Mixed number x Mixed number

2 1/3 x 2 2/3

First you convert the mixed numbers to improper fractions.

2 x 3 = 6
6 + 1 = 7
= 7/6

2 x 3 = 6
6 + 2 = 8
= 8/7

Then you multiply the two improper fractions .

7/6 x 8/7 = 56/42 or 4/3 or 1 1/3

------------------------------------------------------------------------------------------------
Part 3

Division

When you're dividing fractions you multiply the numerators by the denominator in the other fraction.

ex.

3/4 divided 1/2

You multiply 3 x 2 and 1 x 4 = 6/4

Then you make it a mixed fraction.

6/4 = 1 1/2

1 1/2 divided by 3/4

First you have to convert the mixed number to a improper fraction.

3/2 x 3/4

3 x 4 = 12

3 x 2 = 6

= 12/6

or 2
