Пошаговое объяснение:

5 4/9 - 5 = 4/9

1 - 1/7 = 7/7 - 1/7 = 6/7

1 - 2/9 = 9/9 - 2/9 = 7/9

3 - 5/9 = 2 + 1 - 5/9 = 2 + 9/9 - 5/9 = 2 4/9

4 2/5 - 2/5 = 4

1 - 1/15 = 15/15 - 1/15 = 14/15

1 - 3/11 = 11/11 - 3/11 = 8/11

9 - 5 7/8 = 3 + 1 + 5 - 5 7/8 = 3 + 8/8 - 7/8 = 3 1/8

8 9/10 - 3 3/10 = 8 - 3 + 9/10 - 3/10 = 5 6/10 = 5 3/5

1 - 1/12 = 12/12 - 1/12 = 11/12

1 - 5/16 = 16/16 - 5/16 = 11/16

6 4/9 - 3 5/9 = 5 + 1 - 3 + 4/9 - 5/9 = 2 + 9/9 + 4/9 - 5/9 = 2 + 13/9 - 5/9 = 2 8/9
