B)5% de R$400,00
C)1% de R$599,00
D)34% de R$ 712,00
E) 50% de R$800,00

Answer 1

Olá.

→ Segue as contas abaixo ↓

a) 10% de 980

10/100 × x/980

100x = 10 × 980

100x = 9800

x = 9800 ÷ 100

x = 98

b) 5% de 400

5/100 × x/400

100x = 5 × 400

100x = 2000

x = 2000 ÷ 100

x = 20

c) 1% de 599

1/100 × x/599

100x = 1 × 599

100x = 599

x = 599 ÷ 100

x = 5,99

d) 34% de 712

34/100 × x/712

100x = 34 × 712

100x = 24208

x = 24208 ÷ 100

x = 242,208

e) 50% de 800

50/100 × x/800

100x = 50 × 800

100x = 40000

x = 40000 ÷ 100

x = 400
