Let’s solve each problem step by step. All these problems are adding fractions with
like denominators — that means the bottom numbers (denominators) are the same. When denominators are the same, you just add the top numbers (numerators) and keep the denominator the same. Then simplify if needed.
---
1. ¼ + ¼ = (1+1)/4 = 2/4 → Simplify: divide numerator and denominator by 2 →
½
2. 2/3 + 1/3 = (2+1)/3 = 3/3 =
1
3. 1/8 + 4/8 = (1+4)/8 = 5/8 → Already simplified →
5/8
4. 3/14 + 1/14 = (3+1)/14 = 4/14 → Simplify: divide by 2 →
2/7
5. 13/20 + 13/20 = (13+13)/20 = 26/20 → Simplify: divide by 2 → 13/10 → or as mixed number:
1 3/10
6. 3/5 + 4/5 = (3+4)/5 = 7/5 → Mixed number:
1 2/5
7. 68/100 + 24/100 = (68+24)/100 = 92/100 → Simplify: divide by 4 →
23/25
8. 4/6 + 5/6 = (4+5)/6 = 9/6 → Simplify: divide by 3 → 3/2 → Mixed number:
1 ½
9. 2/10 + 2/10 = (2+2)/10 = 4/10 → Simplify: divide by 2 →
2/5
10. 9/50 + 24/50 = (9+24)/50 = 33/50 → Already simplified →
33/50
11. 4/12 + 6/12 = (4+6)/12 = 10/12 → Simplify: divide by 2 →
5/6
12. 2/11 + 1/11 = (2+1)/11 = 3/11 → Already simplified →
3/11
13. 1/2 + 1/2 = (1+1)/2 = 2/2 =
1
14. 3/9 + 5/9 = (3+5)/9 = 8/9 → Already simplified →
8/9
15. 10/13 + 8/13 = (10+8)/13 = 18/13 → Mixed number:
1 5/13
16. 4/7 + 6/7 = (4+6)/7 = 10/7 → Mixed number:
1 3/7
17. 2/15 + 11/15 = (2+11)/15 = 13/15 → Already simplified →
13/15
18. 2/10 + 1/10 = (2+1)/10 = 3/10 → Already simplified →
3/10
19. 14/25 + 2/25 = (14+2)/25 = 16/25 → Already simplified →
16/25
20. 5/7 + 4/7 = (5+4)/7 = 9/7 → Mixed number:
1 2/7
21. 2/5 + 2/5 = (2+2)/5 = 4/5 → Already simplified →
4/5
