Пошаговое объяснение:

1)

2х/36 = 5/6

2х * 6 = 36 * 5

12х = 180

х = 180 : 12

х = 15

2)

4/9 = 3х/54

3х * 9 = 54 * 4

27х = 216

х = 216 : 27

х = 8

3)

7/21 = 3х/54

3х * 21 = 54 * 7

63х = 378

х = 378 : 63

х = 6

4)

11/33 = 2/3х

3х * 11 = 2 * 33

33х = 66

х = 66 : 33

х = 2

5)

8/5 = 4х/15

4х * 5 = 15 * 8

20х = 120

х = 120 : 20

х = 6

6)

9/16 = 3х/64

3х * 16 = 64 * 9

48х = 576

х = 576 : 48

х = 12
