D – Never!

B – When adding and subtracting

What is the sum of 2/3 + 4/5?

A – 22/15

B – 6/8

C – 8/15

D – 2/15

A – 22/15

Find 1/5 of 2/7

A – 3/12

B – 2/12

C – 2/10

D – 2/35

D – 2/35

Find the quotient of 2/3 divided by 4/5.

When you multiply two regular fractions,

(not improper) what is something we

- The answer will be less than both

the fractions you multiplied together

- The answer’s numerator is the product

of fractions’ numerators and the denominator is the product

of the fractions’ denominators!

Find the sum of 2 ¾ + 3 ½

6 ¼

Because: 2 + 3 = 5

¾ + ½ = 1 ¼

Total = 6 ¼

Find the difference between:

5 1/3 and 2 3/4

2 7/12

Because: 5 1/3 – 2 3/4 cannot

be done without borrowing or

turning them both to improper fractions!

Find the product of 3 ½ and 2 ¼

63/8 or 7 7/8

Because:

3 ½ x 2 ¼ becomes…

7/2 x 9/4 = 63/8

Divide 2/3 of a bag of candy among 5 classmates.

• 2/15 of a bag per person

• Because: 2/3 divided by 5 becomes…

• 2/3 x 1/5 = 2/15

How would you divide 3 ¼ bags of popcorn among you and 2 friends?

Each person would get 1 1/12 a bag

Because: 3 ¼ bags divided by 3 people

becomes… 13/4 x 1/3 = 13/12 = 1 1/12

There are 32 students in Ms. Benton’s class. Of the students, 3/8 are boys. How many boys are in her class?

A – 6

B – 8

C – 12

D - 14

C – 12 are boys

Because: 3/8 of24 means…

3/8 x24/1 = 96/8 = 12

Find the difference between

10 2/3 and 8 9/12

1 11/12

Because: You have to borrow or change the fractions to improper fractions before subtracting

Which sum is larger?

4/5 + 5/8 or 4/7 + 5/9

4/5 + 5/8

Because: 4/5 + 5/8 = 1 17/40 (which is almost 1 ½)

and

4/7 + 5/9 = 1 8/63 (which is way less than 1 ½)

Find N if …

N – 1/5 = 7/20

N = 11/20

Because: N – 1/5 = 7/20 can change to…

?/20 – 4/20 = 7/20

And 11- 4 = 7!

Find the quotient of 1/3 divided by 4

by drawing a diagram or using a number line.

0

1

1/3

1/12

In the refrigerator, Tony found 3/4 of a pizza. He ate 1/6 of what was left. How much of the pizza did he eat?

A – 1/24

B – 1/8

C – 1/4

D – 1/3

B – 1/8 of the pizza

Because: 1/6 of 3/4 means…

1/6 x 3/4 = 3/24 = 1/8

Mr. Stewart needs to make 3 apple pies for a bake sale. Each apple pie needs 2 ¼ cups of flour.

How much flour will he need in all?

6 ¾ cups of flour is needed

Because: 3 x 2 ¼ = 3/1 x 9/4 = 27/4 = 6 ¾

Carletta bought 14 yards of string to make shoelaces for her basketball team. She estimates that it takes 2/5 a yard to make one shoelace. How many shoelaces can she make?

35 shoelaces

Because: 14 divided by 2/5 becomes…

14/1 x 5/2 = 70/2 = 35

(Remember, Keep, Change, Change!)

The Comfy Couch Furniture store purchased 3 1/5 pages in the newspaper to advertise their upcoming sale. They then decided to cancel 1 7/10 pages. How many pages did they actually use?

They used 1 ½ pages for advertising

Sammy’s mother bought 4 1/3 pounds of strawberries to make smoothies. She estimates that she will need 1/9 pound of strawberries for each smoothie.

How many smoothies can she make?

She can make 30 smoothies!
