Verified answer

Ответ: x = 3

Пошаговое объяснение:

8x : 4 2/3 = 2 1/7 : 5/12

8x : 14/3 = 15/7 * 12/5

8x * 3/14 = 3/7 * 12/1

4x * 3/7 = 36/7

4/1x * 3/7 =

12/7x = 36/7

x = 36/7 : 12/7

x = 36/7 * 7/12

x = 3/1 * 1/1

x = 3

Ответ:

3

Пошаговое объяснение:

8х : 4 2/3 = 2 1/7 : 5/12

8х * 5/12 = 4 2/3 * 2 1/7

40/12х = 14/3 * 15/7

10/3х = 2/1 * 5/1

10/3х= 10

х = 10 : 10/3

х = 10 * 3/10

х = 30/10

х = 3
