Answer 2

Resposta:

a) 45% de 200 = 90

200 = 100%

x = 45%

100x = 9000

x = 90

b) 30% de 150 = 45

100% = 150

30% = x

100x = 4500

x = 45

c) 50% de 1200 = 600

100% = 1200

50% = x

100x = 60000

x = 600

d) 35% de 1000 = 350

100% = 1000

35% = x

100x = 35000

x = 350

e) 12% de 120​ = 14,4

100% = 120

12% = x

100x = 1440

x = 14,4
