Adding Fractions With The Same Denominator Worksheet for 6th - 8th ... - Free Printable

Let’s solve each problem step by step. All these problems involve adding fractions that have the same denominator — which makes it easy! You just add the numerators (the top numbers) and keep the denominator (the bottom number) the same. Then, if possible, simplify the answer to a mixed number or whole number.

We’ll go one by one:

---

1) 2/3 + 2/3 = (2+2)/3 = 4/3 → 4 ÷ 3 = 1 with remainder 1 → 1 1/3

2) 1/2 + 1/2 = (1+1)/2 = 2/2 = 1

3) 4/5 + 3/5 = (4+3)/5 = 7/5 → 7 ÷ 5 = 1 with remainder 2 → 1 2/5

4) 2/7 + 2/7 = (2+2)/7 = 4/7 → already simplified → 4/7

5) 1/9 + 2/9 = (1+2)/9 = 3/9 → simplify: divide numerator and denominator by 3 → 1/3

6) 3/8 + 5/8 = (3+5)/8 = 8/8 = 1

7) 2/5 + 4/5 = (2+4)/5 = 6/5 → 6 ÷ 5 = 1 with remainder 1 → 1 1/5

8) 7/15 + 2/15 = (7+2)/15 = 9/15 → simplify: divide by 3 → 3/5

9) 1/9 + 3/9 = (1+3)/9 = 4/9 → already simplified → 4/9

10) 1/12 + 2/12 = (1+2)/12 = 3/12 → simplify: divide by 3 → 1/4

11) 1/5 + 3/5 + 2/5 = (1+3+2)/5 = 6/5 → 6 ÷ 5 = 1 with remainder 1 → 1 1/5

12) 1/2 + 2/2 + 1/2 = (1+2+1)/2 = 4/2 = 2

13) 3/4 + 1/4 + 2/4 = (3+1+2)/4 = 6/4 → simplify: 6÷2=3, 4÷2=2 → 3/2 → 3 ÷ 2 = 1 with remainder 1 → 1 1/2

14) 5/6 + 2/6 + 2/6 = (5+2+2)/6 = 9/6 → simplify: divide by 3 → 3/2 → 1 1/2

15) 4/7 + 2/7 + 2/7 = (4+2+2)/7 = 8/7 → 8 ÷ 7 = 1 with remainder 1 → 1 1/7

16) 4/9 + 7/9 + 2/9 = (4+7+2)/9 = 13/9 → 13 ÷ 9 = 1 with remainder 4 → 1 4/9

17) 11/12 + 1/12 + 1/12 = (11+1+1)/12 = 13/12 → 13 ÷ 12 = 1 with remainder 1 → 1 1/12

18) 4/5 + 1/5 + 2/5 = (4+1+2)/5 = 7/5 → 7 ÷ 5 = 1 with remainder 2 → 1 2/5

19) 7/8 + 3/8 + 3/8 = (7+3+3)/8 = 13/8 → 13 ÷ 8 = 1 with remainder 5 → 1 5/8

20) 7/15 + 1/15 + 2/15 = (7+1+2)/15 = 10/15 → simplify: divide by 5 → 2/3
