Question

-3/11х=6/55
7/8х=-1(ціла) 5/16
-8/25х=-2/5

Answer 1

Пошаговое объяснение:

-3/11х = 6/55

х = 6/55 : (-3/11)

х = 6/55 * (-11/3)

х = 2/5 * (-1/1)

х = -2/5

7/8х = 1 5/16

7/8х = 21/16

х = 21/16 : 7/8

х = 21/16 * 8/7

х = 3/2 * 1/1

х = 3/2

х = 1 1/2

-8/25х = -2/5

х = -2/5 : (-8/25)

х = -2/5 * (-25/8)

х = -1/1 * (-5/4)

х = 5/4

х = 1 1/4
