7 1/6

Пошаговое объяснение:

1) 53 3/4 + 9 1/6 = 53 9/12 + 9 2/12 = 62 11/12

2) 62 11/12 * 1 1/5 = 755/12 * 6/5 = 151/2

3) 10 3/10 - 8 1/2 = 10,3 - 8,5 = 1,8

4) 1,8 * 5/9 = 18/10 * 5/9 = 1

5) 151/2 : 1 = 151/2

6) 6 4/5 - 3 3/7 = 6 28/35 - 3 15/35 = 3 13/35

7) 3 13/35 * 5 5/6 = 118/35 * 35/6 = 59/3

8) 3 2/3 - 3 1/6 = 3 4/6 - 3 1/6 = 3/6 = 1/2

9) 59/3 : 1/2 = 59/3 * 2/1 = 118/3

10) 151/2 - 118/3 = 453/6 - 236/6 = 217/6 = 36 1/6

11) 36 1/6 - 29 = 7 1/6
