Пошаговое объяснение:

7/8 - 1/4 = 7/8 - 2/8 = 5/8

9/10 - 3/5 = 9/10 - 6/10 = 3/10

3/4 - 1/8 = 6/8 - 1/8 = 5/8

------------------------------

5/6 - 3/8 = 20/24 - 9/24 = 11/24

3/10 - 2/25 = 15/50 - 4/50 = 11/50

2/9 - 2/15 = 10/45 - 6/45 = 4/45

-----------------------

1/3 - 1/5 = 5/15 - 3/15 = 2/15

4/7 - 3/10 = 40/70 - 21/70 = 19/70

8/15 - 1/2 = 16/30 - 15/30 = 1/30
