Let’s solve each fraction addition problem step by step. Remember: when adding fractions with the same denominator, you just add the numerators and keep the denominator the same.

Row 1:
1.
2/9 + 4/9 = (2+4)/9 = 6/9 → Simplify: divide numerator and denominator by 3 → 2/3
2.
3/5 + 1/5 = (3+1)/5 = 4/5
3.
2/7 + 3/7 = (2+3)/7 = 5/7
4.
3/8 + 1/8 = (3+1)/8 = 4/8 → Simplify: divide by 4 → 1/2
---
Row 2:
5.
2/8 + 3/8 = (2+3)/8 = 5/8
6.
3/10 + 1/10 = (3+1)/10 = 4/10 → Simplify: divide by 2 → 2/5
7.
1/2 + 1/2 = (1+1)/2 = 2/2 = 1
8.
1/3 + 1/3 = (1+1)/3 = 2/3
---
Row 3:
9.
2/5 + 1/5 = (2+1)/5 = 3/5
10.
1/4 + 2/4 = (1+2)/4 = 3/4
11.
1/3 + 1/3 = (1+1)/3 = 2/3
12.
2/6 + 1/6 = (2+1)/6 = 3/6 → Simplify: divide by 3 → 1/2
---
Row 4:
13.
1/2 + 1/2 = (1+1)/2 = 2/2 = 1
14.
3/10 + 2/10 = (3+2)/10 = 5/10 → Simplify: divide by 5 → 1/2
15.
2/7 + 3/7 = (2+3)/7 = 5/7
16.
2/8 + 1/8 = (2+1)/8 = 3/8
---
Row 5:
17.
3/5 + 1/5 = (3+1)/5 = 4/5
18.
2/6 + 2/6 = (2+2)/6 = 4/6 → Simplify: divide by 2 → 2/3
19.
1/4 + 1/4 = (1+1)/4 = 2/4 → Simplify: divide by 2 → 1/2
20.
1/3 + 1/3 = (1+1)/3 = 2/3
---
Final Answer:
Row 1: 2/3, 4/5, 5/7, 1/2
Row 2: 5/8, 2/5, 1, 2/3
Row 3: 3/5, 3/4, 2/3, 1/2
Row 4: 1, 1/2, 5/7, 3/8
Row 5: 4/5, 2/3, 1/2, 2/3
