1 / 6 - 3 / 5 x 7 / 9 равно​

это вопрос?

1) 8 7/9 - х = 3 5/6

х = 8 7/9 - 3 5/6

х = 8 14/18 - 3 15/18

х = 7 32/18 - 3 15/18

х = 4 17/18

- - - - - - -

Проверка: 8 14/18 - 4 17/18 = 7 32/18 - 4 17/18 = 3 15/18 = 3 5/6

2) (х - 5/6) + 11/18 = 19/24

х - 5/6 = 19/24 - 11/18

х - 5/6 = 57/72 - 44/72

х - 5/6 = 13/72

х = 13/72 + 5/6

х = 13/72 + 60/72

х = 73/72

х = 1 целая 1/72

Проверка: (73/72 - 60/72) + 44/72 = 57/72 = 19/24
