Answer 1

2/7 + 1/2 = (4 + 7)/14 = 11/14

1/5 + 4/10 = (10 + 20)/50 = 30/50 = 3/5

1/4 + 1/2 = (2 + 4)/8 = 6/8 = 3/4

1/4 + 2/3 = (3 + 8)/12 = 11/12

2/9 + 2/3 = (2 + 6)/9 = 8/9

2/3 - 1/4 = (8 - 3)/12 = 5/12

2/3 - 1/4 = (8 - 3)/12 = 5/12

5/6 - 2/3 = (5 - 4)/6 = 1/6

5/6 - 1/2 = (5 - 3)/6 = 2/6 = 1/3

2/4 - 1/2 = (2 - 1)/4 = 1/4

3/6 + 5/8 = (12 + 15)/24 = 27/24 = 9/8

3/6 + 1/2 = (3 + 3)/6 = 6/6 = 1
