Question

calcule os valores desconhecidos: a) 2/3 = 18/x b) 8/x = 24/33 c) x/9 = 5/3 d) 1/2 = x/10

Answer 1

a) 2/3=18/x -> 2x=3*18 -> x=27

b) 8/x=24/33 -> 24x=8*33 -> 3x=33 -> x=11

c)x/9=5/3 -> 3x=45 -> x=15

d) 1/2=x/10 -> 2x=10 -> x=5

Answer 2

Tarefa

Explicação passo-a-passo:

calcule os valores desconhecidos:

a) 2/3 = 18/x

2x = 3*18

x = 3*18/2 = 3*9 = 27

b) 8/x = 24/33

8/x = 8/11

x = 11

c) x/9 = 5/3

3x = 9*5 = 45

x = 45/3 = 15

d) 1/2 = x/10

2x = 10

x = 10/2 = 5
