Answer 1

$a) \: \frac{4}{20} = \frac{4}{20} \: . \: \frac{5}{5} = \frac{4 \: . \: 5}{20 \: . \: 5} = \frac{20}{100} = \boxed{\boxed{\boxed{20\%}}} \\ b) \: \frac{13}{50} = \frac{13}{50} \: . \: \frac{2}{2} = \frac{13 \: . \: 2}{50 \: . \: 2} = \frac{26}{100} = \boxed{\boxed{\boxed{26\%}}} \\ c) \: \frac{8}{25} = \frac{8}{25} \: . \: \frac{4}{4} = \frac{8 \: . \: 4}{25 \: . \: 4} = \frac{32}{100} = \boxed{\boxed{\boxed{32\%}}} \\ d) \: \frac{61}{10} = \frac{61}{10} \: . \: \frac{10}{10} = \frac{61 \: . \: 10}{10 \: . \: 10} = \frac{610}{100} = \boxed{\boxed{\boxed{610\%}}}$

Explicação passo-a-passo:

a) 4/20 = 4/20 * 5/5 = 20/100 = 20%

b) 13/50 = 13/50 * 2/2 = 26/100 = 26%

c) 8/25 = 8/25 * 4/4 = 32/100 = 32%
