A) 45% de 65

B) 60% de 150

C) 8% de 18​

Answer 1

Resposta:

A = 29,25   B = 90   C = 1,44

Explicação passo-a-passo:

A)

45% de 65

65 - 100%

x - 45%

100x = 65.45

100x = 2925

x = 2925 / 100

x = 29,25

-------------------------------------

B)

60% de 150

150 - 100%

x - 60%

100x = 150.60

100x = 9000

x = 9000/100

x = 90

-------------------------------------

C)

8% de 18

18 - 100%

x - 8%

100x = 18.8

100x = 144

x = 144 / 100

x = 1,44
