Question

Найдите неизвестный член пропорции:-2_3/7:х=1_13/14:6/17

Answer 1

-2 3/7:х=1 13/14:6/17
1 13/14*х=-2 3/7*6/17
27/14*х=-17/7*6/17
27/14*х=-6/7
х=-6/7:27/14
х=-12/27
х=-4/9

Верно

Answer 2

- 2 3/7 : Х = 1 13/14 : 6/17
1 13/14 : 6/17 = 27/14 : 6/17 = 459/84
- 2 3/7 : Х = 459/84
Х = - 2 3/7 : 459/84
Х = - 17/7 : 459/84
Х = - 84/189
Х = - 12/27
