Answer 1

1) 5/17 + 5/34 = 5*2 + 5/34 = 15/34

2) 7/12 + 17/36 = 7*3 + 17/36 = 38/36

3) 2/5 + 13/20 = 2*6 + 13/20 = 25/20

4) 3/7 + 9/28 = 3*4 + 9/28 = 21/28

5) 2/3 + 4/5 = 2*5 + 4*3/15 = 22/15

6) 3/7 + 3/5 = 3*5 + 3*7/35 = 36/35

7) 2/11 + 5/7 = 2*7 + 5*11/77 = 69/77

8) 3/4 + 1/6 = 3*4 + 1*2/12 = 14/12

9) 5/6 + 7/8 = 5*4 + 7*3/24 = 41/24

10) 3/10 + 5/8 = 3*4 + 5*5/40 = 37/40

11) 11/12 + 3/8 = 11*2 + 3*3/24 = 31/24

12) 11/24 + 5/28 = 11*7 + 5*6/168 = 107/168
