Answer 2

Resposta:

a)

$15\% \: de \: 4720 = 708 \\ 15 \div 10 = 1.5 \\ 4720 \div 10 = 472 \\ 1.5 \times 472 = 708$

B)

$25\% \: de \: 12850 = 3.212.5 \\ 25 \div 10 = 2.5 \\ 12850 \div 10 = 1.285 \\ 2.5 \times 1.285 = 3.212.5$

C)

$82\% \: de \: 4.1800 = 34.276 \\ 82 \div 10 = 8.2 \\ 4.1800 \div 10 = 4.180 \\ 8.2 \times 4.180 = 34.276$

D)

$7.5\% \: de \: 90 = 6.75 \\ 7.5 \div 10 = 0.75 \\ 90 \div 10 = 9 \\ 0.75 \times 9 = 6.75$

E)

$12.5\% \: de \: 610 = 76.25 \\ 12.5 \div 10 = 1.25 \\ 610 \div 10 = 61 \\ 1.25 \times 61 = 76.25$
