Resposta:

> Utilizando a Regra de Três:

20% de 300

300________100%

x__________20%

100x = 300 × 20

100x = 6000

x = 6000 ÷ 100

x = 60

10% de 300

300_______100%

x__________10%

100x = 300 × 10

100x = 3000

x = 3000 ÷ 100

x = 30

30% de 300

300_______100%

x_________30%

100x = 300 × 30

100x = 9000

x = 9000 ÷ 100

x = 90

15% de 300

300_______100%

x__________15%

100x = 300 × 15

100x = 4500

x = 4500 ÷ 100

x = 45
