Question

141. 1) 17 x: 3,5 = : 1,02; 35 3 11 2) (6,5 + x): 0,475 = 119 3 28​

Answer 1

Ответ:

1.9 2/3 -х = 50/51*17/35*3,5

29/3-х=50/3*1/35*7/2

29/3-х25/3*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= 10 30\/19*28/3\

(6,5+х):0,475=280/19

(6,5+х)=70\280/19*19/4

6,5+х=70

х=70-6,5

х= 63,5
