Пошаговое объяснение:

5 4/5 + 2 1/3 = 5 12/15 + 2 5/15 = 7 17/15 = 8 2/15

7 5/7 + 5 1/2 = 7 10/14 + 5 7/14 = 12 17/14 = 13 3/14

11 3/4 + 3 2/7 = 11 21/28 + 3 8/28 = 14 29/28 = 15 1/28

4 3/5 + 5 2/3 = 4 9/15 + 5 10/15 = 9 19/15 = 10 4/15

7 8/15 - 5 2/5 = 7 8/15 - 5 6/15 = 2 2/15

12 2/5 - 9 3/10 = 12 4/10 - 9 3/10 = 3 1/10

8 7/12 - 6 3/4 = 8 7/12 - 6 9/12 = 7 19/12 - 6 9/12 = 1 10/12 = 1 5/6

10 3/4 - 5 3/8 = 10 6/8 - 5 3/8 = 5 3/8
