Question

calcule as porcentagens 4% de20 6% de 100 70% de 100

Answer 1

• 4% de 20

20 = 100%

x = 4%

100x = 20 . 4

100x = 80

x = 80 / 100

x = 0,8

• 6% de 100

100 = 100%

x = 6%

100x = 100 . 6

100x = 600

x = 600 / 100

x = 6

• 70% de 100

100 = 100%

x = 70%

100x = 100 . 70

100x = 7 000

x = 7 000 / 100

x = 70
