Пошаговое объяснение:

1) 3. 3/4 * 3/4 = 15/4 * 3/4 = 45/16 = 2. 13/16

2) 8. 4/9 : 3. 4/5 =

76/9 : 19/5 = 76/9 * 5/19 =

4/9 * 5/1 = 20/9 = 2. 2/9

3) 1. 1/2 : 27 = 3/2 : 27 =

3/2 * 1/27 = 1/2 * 1/9 = 1/18

4) 2. 13/16 - 2. 2/9 + 1/18 =

2. 117/144 - 2. 32/144 + 8/144 =

85/144 + 8/144 = 93/144 = 31/48

5) 31/48 : 1. 29/48 =

31/48 : 77/48 = 31/48 * 48/77 = 31/77

Ответ: 31/77
