Verified answer

Пошаговое объяснение:

1 : 3 = х : 6

3 * х = 1 * 6

3х = 6

х = 6 : 3

х = 2

7/2 = 35/х

7 * х = 2 * 35

7х = 70

х = 70 : 7

х = 10

3 1/8 : 2 1/2 = 2 2/3 : х

3 1/8 * х = 2 1/2 * 2 2/3

25/8 * х = 5/2 * 8/3

25/8х = 40/6

х = 40/6 : 25/8

х = 40/6 * 8/25

х = 8/3 * 4/5

х = 32/15

х = 2 2/15
