Найдите корень уравнения

1) 6/5x=3/5

2) 4/7x=1

3) 3/4x=12

4) x:7/15=15/28

5) 5 1/4:x=7/8

6) 3 3/7:x=1 5/7

1) 6/5x=3/5

6/5x : 3/5 = 3/5 : 3/5

6/5x * 5/3 = 1

6/3x = 1

2x = 1

x = 0,5

2) 4/7x=1

4x = 7

x = 7/4

x = 1,75

3) 3/4x=12

3x = 48

x = 16

4) x:7/15=15/28

x * 15/7 = 15/28

60x = 15

x = 0,25

5) 5 1/4:x=7/8

5 2/8 : x = 7/8

7/x = 7/8

56 = 7x

x = 8

6) 3 3/7:x=1 5/7

6/x = 6

6 = 6x

x = 1
