Answer 1

Пошаговое объяснение:

5 3/8 + 6 7/9 = 5 27/72 + 6 56/72 = 11 83/72 = 12 11/72

10 3/6 - 3 7/5 = 10 1/2 - 4 2/5 = 10 5/10 - 4 4/10 = 6 1/10

11 8/9 + 15 9/10 = 11 80/90 + 15 81/90 = 26 161/90 = 27 71/90

20 - 21/22 = 21 22/22 - 21/22 = 21 1/22

16 5/7 - 2 2/5 = 16 25/35 - 2 14/35 = 14 11/35
