Помогите пожалуйста​

Answer 1

Ответ:

1) 25/27х = 5/18

х = 5/18 : 25/27

х = 5/18 • 27/25

х = 1/6 • 9/5

х = 9/30

х = 3/10

х = 0,3

2) 13/17х = 39

х = 39 : 13/17

х = 39/1 • 17/13

х = 3/1 • 17/1

х = 51

3) 4х = 5/7

х = 5/7 : 4

х = 5/7 • 1/4

х = 5/28

4) х : 2 2/15 = 1 9/16

х = 2 2/15 • 1 9/16

х = 32/15 • 25/16

х = 2/3 • 5/1

х = 10/3

х = 3 1/3

5) 4 4/9 : х = 5/27

х = 4 4/9 : 5/27

х = 40/9 • 27/5

х = 8/1 • 3/1

х = 24

6) 1 4/9х = 5,2

х = 5,2 : 1 4/9

х = 52/10 • 9/13

х = 4/10 • 9/1

х = 36/10

х = 3 6/10

х = 3,6
