Answer 2

Explicação passo-a-passo:

A)

$\frac{20}{4} \div 5 = \frac{20}{4} \times \frac{5}{1} = \frac{100}{4} = 25$

B)

$\frac{4}{5} \div \frac{1}{2} = \frac{4}{5} \times \frac{2}{1} = \frac{8}{5}$

C)

$\frac{12}{35} + \frac{6}{5} = \frac{12}{35} + \frac{42}{35} = \frac{54}{35}$

D)

$\frac{2}{3} \div \frac{1}{3} = \frac{2}{3} \times \frac{3}{1} = \frac{6}{3} = 2$

E)

$\frac{4}{7} \div \frac{5}{3} = \frac{4}{7} \times \frac{3}{5} = \frac{12}{35}$
