Answer 1

1)

4 * x = 3 * 8/9

4x = 8/3

x = 8/3 * 1/4

x = 2/3

2)

7 * x = 5 * 2,8

7x = 14

x = 14 : 7

x = 2

3)

12 * x = 9 * 7

12x = 63

x = 63 : 12

x = 5,25

4)

5,2 * x = 8 * 6,5

5,2x = 52

x = 52 : 5,2

x = 10

5)

3,6 * x = 4,5 * 4

3,6x = 18

x = 18 : 3,6

x = 5

6)

4 * x = 15 * 1 1/3

4x = 15 * 4/3

4x = 20

x = 20 : 4

x = 5
