Answer 1

Пошаговое объяснение:

1/2 - 2/5 = 5/10 - 4/10 = 1/10

1/4 - 1/5 = 5/20 - 4/20 = 1/20

3/5 - 2/7 = 21/35 - 10/35 = 11/35

8/9 - 7/15 = 40/45 - 21/45 = 19/45

7/11 - 4/7 = 49/77 - 44/77 = 5/77

19/20 - 13/15 = 57/60 - 52/60 = 5/60 = 1/12

11/18 - 11/30 = 55/90 - 33/90 = 22/90 = 11/45

17/24 - 19/60 = 85/120 - 38/120 = 47/120
