Let’s solve each problem step by step. Since all these problems are about adding fractions with
like denominators (same bottom number), we just add the top numbers (numerators) and keep the bottom number (denominator) the same.

1) 3/5 + 1/5 = (3+1)/5 =
4/5
2) 1/6 + 4/6 = (1+4)/6 =
5/6
3) 2/7 + 3/7 = (2+3)/7 =
5/7
4) 3/8 + 5/8 = (3+5)/8 =
8/8 → which simplifies to
1
5) 2/5 + 2/5 = (2+2)/5 =
4/5
6) 3/10 + 7/10 = (3+7)/10 =
10/10 → which simplifies to
1
7) 2/9 + 5/9 = (2+5)/9 =
7/9
8) 6/11 + 3/11 = (6+3)/11 =
9/11
9) 7/20 + 13/20 = (7+13)/20 =
20/20 → which simplifies to
1
10) 2/7 + 4/7 = (2+4)/7 =
6/7
11) 11/20 + 3/20 = (11+3)/20 =
14/20 → simplify by dividing numerator and denominator by 2 →
7/10
12) 5/12 + 7/12 = (5+7)/12 =
12/12 → which simplifies to
1
13) 4/15 + 4/15 = (4+4)/15 =
8/15
14) 6/25 + 11/25 = (6+11)/25 =
17/25
15) 7/11 + 3/11 = (7+3)/11 =
10/11
16) 5/13 + 6/13 = (5+6)/13 =
11/13
17) 8/25 + 9/25 = (8+9)/25 =
17/25
18) 27/100 + 32/100 = (27+32)/100 =
59/100
