Question

1) - Represente as frações abaixo na forma percentual.
a) 7/10 b) 1/5 c) 3/20 d) 3/4 e) 1/8

Answer 1

Resposta:

a) $\frac{7}{10}$ x 10 = $\frac{70}{100}$ = 70%

b) $\frac{1}{5}$ x 10 = $\frac{10}{50}$ x 2 = $\frac{20}{100}$ = 20%

c) $\frac{3}{20}$ x 5 = $\frac{15}{100}$ = 15%

d) $\frac{3}{4}$ x 5 = $\frac{15}{20}$ x 5 = $\frac{75}{100}$ = 75%

e) $\frac{1}{8}$ x 12,5 = $\frac{125}{1000}$ = 12,5%
