Answer 1

Пошаговое объяснение:

№5

8/15 * 5/32 = 1/3 * 1/4 = 1/12

1/8 : 1/7 = 1/8 * 7/1 = 7/8

12 * 1/360 = 12/360 = 1/30

№6

(2/5х - 2 2/3) * 15 = 2

2/5х - 2 2/3 = 2/15

2/5х = 2/15 + 2 2/3

2/5х = 2/15 + 2 10/15

2/5х = 2 12/15

2/5х = 2 4/5

х = 2 4/5 : 2/5

х = 14/5 * 5/2

х = 7/1 * 1/1

х = 7/1

х = 7
