Question

Задание номер девять

Answer 1

1) 5/8-2/3=15/24-16/24=-1/24

2)2 1/3 : 1/24=7/3*24=56

3)2*1 3/7= 2 6/7

4)56-2 6/7=53 1/7

Answer 2

5/8 - 8/3 = 15/24 - 64/24 = - 49/24
2 1/3 = 7/3
7/3 : (- 49/24) = - 7/3 х 24/49 = - 8/7
2 х 1 3/7 = 2 х 10/7 = 20/7
- 8/7 - 20/7 = - 28/7 = - 4
ответ: - 4
