1) (9 2/4- x) : 3,5 = 17/35 : 1,02=
2) (6,5 + x) : 0,475 = 1 11/19 : 3/28 = ​

Ответ:

1) 29/3-х=50/51•1/35•7/2

29/3-х=25/3•1/5

29/3-х=5/3

-х=5/3-29/3

-х=-8

х=8

2)  (6,5+х):0,475=1 11/19:3/28. ​

(6,5+х):0,475=30/19*28/3

(6,5+х):0,475=280/19

6.5+x=280/19*0.475

6.5+x=280/19*19/40

6.5+x=7

х=7-6.5

х=0.5
