Explicação passo-a-passo:

A)

3/5 = x/20

20/5 = 4

4 x 3 = 12

12/20

E)

18/45 = x /5

45x = 90

x = 90/45

x = 2

2/5

F)

4/8 = 1/x

4x = 8

x = 8/4

x = 2

1/2

G)

x/8 = 10/8

8x = 80

x = 80/8

x = 10

10/8

H)

5/5 = 3/x

5x = 15

x = 15/5

x = 3

3/3

I)

6/10 = 9/x

6x = 90

x = 90/6

x = 15

9/15
