Worksheet on Adding Fractions with Common Denominators

Practice the worksheet on adding fractions with common denominators where only the numerators are added and the denominators will remain same.

Follow the rules to find the sum of the fractions: $$Sum  of  fractions  =  \frac{Sum  of  numerators}{Same  denominators}$$

To solve the questions follow the above rules to find the fractions having the same denominators with different numerators.

1. Add the following fractions:

(i) 1/5 + 3/5

(ii) 5/11 + 4/11

(iii) 5/7 + 1/7

(iv) 6/15 + 7/15

(v) 17/25 + 7/25

(vi) 10/32 + 9/32

(vii) 1/7 + 2/7 + 3/7

(viii) 4/19 + 6/19 + 3/19

(ix) 4/11 + 5/11 + 7/11

(x) 5/14 + 6/14 + 9/14

2. Find the sum of the following fractions:

(i) 9/16 + 5/16

(ii) 17/25 + 11/25

(iii) 16/17 + 9/17 + 11/17

(iv) 5/9 + 2/9 + 1/9

(v) 3/13 + 8/13 + 12/13

3. Fill in the blanks:

(i) 5/12 + 2/12 = _____

(ii) _____ + 7/2 = 9/2

(iii) 3/35 + 7/35 + 9/35 = _____

(iv) _____ + 9/47 = 22/47

(v) 13/19 + 8/19 + 12/19 = _____
