Ответ:

2 1/36

Пошаговое объяснение:

(2 3/4 + 1 5/8) : 3 1/2 + 3 1/9 * 4/16 = (11/4 + 13/8) : 7/2 + 28/9 * 1/4 =

35/8 : 7/2 + 7/9 = 35/8 * 2/7 + 7/9 = 5/4 + 7/9 = 73/36 = 2 1/36

По действиям:

1. 2 3/4 + 1 5/8 = 11/4 + 13/8 = 35/8

2. 3 1/9 * 4/16 = 28/9 * 1/4 = 7/9

3. 35/8 : 7/2 = 35/8 * 2/7 = 5/4

4. 5/4 + 7/9 = 73/36 = 2 1/36
