Question

Calcule a) 10% de r$ 300 B)90 % de r$ 480,00 c) 10% de r$ 2300 d)30% de r$ 800 e) 20% de 500

Answer 1

Resposta:

a)

$300 \times \frac{10}{100} = 300 \times 10 \div 100 = 3000 \div 100 = 30$

r$30

b)

$480 \times \frac{90}{100} = 480 \times 90 \div 100 = 43200 \div 100 = 432$

r$432

c)

$2300 \times \frac{10}{100} = 2300 \times 10 \div 100 = 23000 \div 100 = 230$

r$230

d)

$800 \times \frac{30}{100} = 800 \times 30 \div 100 = 24000 \div 100 = 240$

r$240

e)

$500 \times \frac{20}{100} = 500 \times 20 \div 100 = 10000 \div 100 = 100$

r$100
