Question

срочно надо проверить ​

Answer 1

1/2 + 1/3 = 5/6

1/4 + 2/5 = 13/20

2/3 + 1/4 = 11/12

Не видно

5/7 - 1/6 = 23/42

3/4 -1/3 = 5/12

1/8 + 1/4 = 3/8

2/3 - 5/9 = 1/9

1/2 - 5/12 = 1/12

1/8 + 7/12 = 17/24

3/4 - 1/6 = 7/12

5/9 + 3/4 = 1 11/36 или 47/36

23/40 - 3/8 = 1/5

9/35 - 3/28 = 357/980
