Let’s solve each fraction addition problem step by step.
Remember: When adding fractions with the
same denominator (bottom number), you just add the
numerators (top numbers) and keep the denominator the same. Then simplify if needed!
---
1. 3/7 + 3/7
Add numerators: 3 + 3 = 6
Keep denominator: 7
→ 6/7
✔
2. 2/5 + 1/5
2 + 1 = 3
→ 3/5
✔
3. 2/9 + 5/9
2 + 5 = 7
→ 7/9
✔
4. 1/6 + 4/6
1 + 4 = 5
→ 5/6
✔
5. 1/4 + 2/4
1 + 2 = 3
→ 3/4
✔
6. 1/3 + 1/3
1 + 1 = 2
→ 2/3
✔
7. 5/7 + 1/7
5 + 1 = 6
→ 6/7
✔
8. 5/12 + 6/12
5 + 6 = 11
→ 11/12
✔
9. 3/5 + 1/5
3 + 1 = 4
→ 4/5
✔
10. 3/8 + 4/8
3 + 4 = 7
→ 7/8
✔
All answers are already in simplest form — no need to reduce further!

1. 6/7
2. 3/5
3. 7/9
4. 5/6
5. 3/4
6. 2/3
7. 6/7
