Question

Calcule o valor de x:
a) 11/3 = 77/x b) 13/25 = x/75 c) x/3 = 20/15 d) 9/8 = 72/x e) 10/14 = 30/x f) 2/7 = x/49
g) 6/16 = 30/x h) x/5 = 8/20
i) 6/x = 18/21 j) 7/12 = x/60

Answer 1

Resposta:

a) 11/3 = 77/x

x=21

b) 13/25 = x/75

x=39

c) x/3 = 20/15

x=4

d) 9/8 = 72/x

x=64

e) 10/14 = 30/x

x=42

f) 2/7 = x/49

x=14

g) 6/16 = 30/x

x=80

h) x/5 = 8/20

x=2

i) 6/x = 18/21

x=7

j) 7/12 = x/60

x=35
