Answer 2

Ответ:

1.  х = 8/9

2. х = 2

Пошаговое объяснение:

1. 4 1/9 - 2х = 2 1/3

-2х = 7/3 - 37/9

-2х = (7*3- 37)/9

-2х = -16/9

х = -16/9 : (-2)

х = -16/9 * (-1/2)

х = 8/9

Проверим:

4 1/9 - 2*8/9  = 2 1/3

4 1/9 - 16/9 = 2 1/3

2 19/9 - 16/9 = 2 1/3

2 3/9 = 2 1/3

2 1/3 = 21/3

2. 3 3/7 : 2/7х = 3 1/3 : 5/9

2/7х = 24/7 : (10/3 : 5/9)

2/7х = 24/7 : 6

2/7х = 4/7

х = 4/7 : 2/7 = 4/7 * 7/2

х = 2

Проверим:

3 3/7 : (2/7*2) = 3 1/3 : 5/9

24/7 : 4/7 = 10/3 : 5/9

24/7 * 7/4 = 10/3 * 9/5

6 = 6
