f) R$ 700,00

Explicação passo-a-passo:

Boa tarde,

Você fará uma regra de 3.

a)6% de 300

300 --- 100%

× --- 6%

100×= 300•6

100×= 1800

×= 1800/100

×= 18

b) 14% de 2100

2100 --- 100%

× --- 14%

100×= 2100•14

100×= 29400

×= 29400/100

×= 294

c) 45% de 8200

8200 --- 100%

× --- 45%

100×= 8200•45

100×= 369000

×= 369000/100

×= 3690

d) 2% de R$ 150,00

150 --- 100%

× --- 2%

100× = 150•2

100×= 300

×= 300/100

×= 3

e) 18% de R$ 6000,00

6000 --- 100%

× --- 18

100×= 6000•18

100×= 108000

×= 108000/100

×= 1080

f) 3,5% de R$ 20000,00

20000 --- 100%

× --- 3,5%

100×= 20000•3,5

100×= 70000

×= 70000/100

×= 700

Bons estudos ❤
