b) 22% de 250
c) 38% de 1200
d) 65% de 3000

Answer 1

Explicação passo-a-passo:

Boa tarde e bons estudos ❤

a) 18% de 100

100 -- 100%

× -- 18%

100× = 100•18

100× = 1800

× = 1800÷100

× = 18

b) 22% de 250

250 -- 100%

× -- 22%

100× = 250•22

100× = 5500

× = 5500 ÷ 100

× = 55

c) 38% de 1200

1200 -- 100%

× -- 38%

100× = 1200•38

100× = 45600

× = 45600 ÷ 100

× = 456

d) 65% de 3000

3000 -- 100%

× -- 65%

100× = 3000 • 65

100× = 195000

× = 195000÷100

×= 1950
