Math worksheet featuring 11 fraction word problems designed for 7th-grade students to practice adding and subtracting fractions in real-world contexts.

Let’s solve each problem one by one, step by step.

Problem 1:

Snow fell twice:
Morning = 3/8 inch
Afternoon = 1/2 inch

We need to add them:
3/8 + 1/2

But we can’t add fractions with different denominators directly. So let’s make the denominators the same.

The least common denominator of 8 and 2 is 8.

Convert 1/2 to eighths:
1/2 = 4/8

Now add:
3/8 + 4/8 = 7/8

✔ Final Answer for Problem 1: B) 7/8

Problem 2:

Simon has:
- Cranberry juice: 1/5 gallon
- Apple juice: 1/3 gallon
- Grape juice: 7/10 gallon

Add them all:
1/5 + 1/3 + 7/10

Find a common denominator. The least common denominator of 5, 3, and 10 is 30.

Convert each fraction:

1/5 = 6/30
1/3 = 10/30
7/10 = 21/30

Now add:
6/30 + 10/30 + 21/30 = 37/30

37/30 is an improper fraction. Let’s turn it into a mixed number:

37 ÷ 30 = 1 with remainder 7 → so 1 7/30

✔ Final Answer for Problem 2: D) 1 7/30

Problem 3:

Rachel had 1/8 bag
Ethan had 2/3 bag
Total = 1/8 + 2/3

Common denominator of 8 and 3 is 24.

Convert:

1/8 = 3/24
2/3 = 16/24

Add:
3/24 + 16/24 = 19/24

✔ Final Answer for Problem 3: A) 19/24

Problem 4:

Three friends ate parts of a pizza:

Mary: 3/8
Jolene: 3/16
Susan: 1/4

First, find how much they ate together.

Common denominator of 8, 16, and 4 is 16.

Convert:

3/8 = 6/16
3/16 = 3/16 (already good)
1/4 = 4/16

Add:
6/16 + 3/16 + 4/16 = 13/16

So they ate 13/16 of the pizza.

How much was left?
Whole pizza = 1 = 16/16
Left = 16/16 - 13/16 = 3/16

✔ Final Answer for Problem 4: D) 3/16

Problem 5:

Kimberly has 80 coins.
She shared 1/8 of her collection equally between two friends.

First, find 1/8 of 80:

80 × 1/8 = 10 coins total to share.

She shares these 10 coins equally between 2 friends:

10 ÷ 2 = 5 coins per friend.

✔ Final Answer for Problem 5: C) 5
