Answer 1

Oi...

Calcule

a)

12% de 300

100x = 12.300

100x = 3 600

x = 3 600/100

x = 36

b)

32% de 450

100x = 32.450

100x = 14 400

x = 14 400/100

x = 144

c)

18% de 500

100x = 18.500

100x = 9 000

x = 9 000/100

x = 90

d)

60% de 80

100x = 60.80

100x = 4 800

x = 4 800/100

x = 48

Bons estudos.
