Answer 1

Vamos là.

a)

3/4 = x/36

4x = 108

x = 108/4 = 27  

b)

7/15 = 42/y

y/42 = 15/7

42y/42 = 42*15/7

y = 6*15 = 90

c)

11/6 = 33/y = x/30

y/33 = 6/11

y =  33*6/11 = 18

x/30 = 11/6

x = 30*11/6 = 5*11 = 55

d)

2/3 = x/24 = 40/y

x/24 = 2/3

24x/24 = 2*24/3 = 2*8 = 16

y/40 = 3/2

y = 40*3/2 = 60
