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

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


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

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 = ?
