3 1/3 x / 1,5 = 4 2/7 ÷ 3/14 ​

Пошаговое объяснение:

3. 1/3х : 1,5 = 4. 2/7 : 3/14

3. 1/3х = 1,5 * 4. 2/7 : 3/14

3. 1/3х = 1. 5/10 * 4. 2/7 : 3/14

10/3х = 15/10 * 30/7 : 3/14

10/3х = 15/1 * 3/7 : 3/14

10/3х = 45/7 : 3/14

10/3х = 45/7 * 14/3

10/3х = 15/1 * 2/1

10/3х = 30

х = 30 : 10/3

х = 30 * 3/10

х = 90/10

х = 9

ответ: 9
