Sure! Let’s solve each of the
Addition of Fractions problems on this worksheet step by step.
All the fractions in each problem have the
same denominator, so we can simply
add the numerators and keep the denominator the same. Then, if possible, we simplify the result.

1 1/5
✔ Answer: 1 1/5
---
🔢 Problem 2:
1/4 + 3/4 + 1/4 = ?
- Numerators: 1 + 3 + 1 =
5
- Denominator: 4 →
5/4
- Simplify: 5/4 =
1 1/4
✔ Answer: 1 1/4
---
🔢 Problem 3:
1/5 + 2/5 + 1/5 = ?
- Numerators: 1 + 2 + 1 =
4
- Denominator: 5 →
4/5
- Already simplified.
✔ Answer: 4/5

🔢 Problem 4:
1/4 + 2/4 + 2/4 = ?
- Numerators: 1 + 2 + 2 =
5
- Denominator: 4 →
5/4
- Simplify:
1 1/4
✔ Answer: 1 1/4

9/9 = 1
✔ Answer: 1
---
🔢 Problem 8:
2/5 + 1/5 + 4/5 = ?
- Numerators: 2 + 1 + 4 =
7
- Denominator: 5 →
7/5
- Simplify:
1 2/5
✔ Answer: 1 2/5
---
🔢 Problem 9:
3/7 + 1/7 + 2/7 = ?
