Fraction Word Problems worksheet for practicing addition of fractions in real-life scenarios.

Let’s solve each problem step by step.

Problem 1:

Mother bought:
- 4/5 kg of fish
- 7/10 kg of prawns

We need to find the total mass, so we add them:

→ 4/5 + 7/10

But we can’t add fractions with different denominators directly. We need a common denominator.

The least common denominator of 5 and 10 is 10.

Convert 4/5 to tenths:

→ 4/5 = (4 × 2) / (5 × 2) = 8/10

Now add:

→ 8/10 + 7/10 = 15/10

Simplify 15/10:

→ 15 ÷ 5 = 3, 10 ÷ 5 = 2 → 3/2

Or as a mixed number: 1 1/2

So total mass = 1 1/2 kg or 1.5 kg

✔ Double-check:
4/5 = 0.8, 7/10 = 0.7 → 0.8 + 0.7 = 1.5 → correct!

Problem 2:

Priscilla uses:
- 3/8 kg for biscuits
- 1/2 kg for cakes

Add them: 3/8 + 1/2

Common denominator of 8 and 2 is 8

Convert 1/2 to eighths:

→ 1/2 = (1 × 4) / (2 × 4) = 4/8

Now add:

→ 3/8 + 4/8 = 7/8

That’s already simplified.

✔ Double-check:
3/8 = 0.375, 1/2 = 0.5 → 0.375 + 0.5 = 0.875 → which is 7/8 → correct!

Final Answer:
1. 1 1/2 kg (or 1.5 kg)
2. 7/8 kg
