Answer 1

Resposta:

Olá boa noite!!!

Explicação passo-a-passo:

A)

$\frac{3}{4} - ( \frac{3}{2} - \frac{1}{4})$

$\frac{3}{4} - \frac{5}{4}$

$- \frac{1}{2}$

B)

$\frac{2}{3} - \frac{2}{8} - (2 + ( \frac{1}{3} + \frac{2}{5))}$

$\frac{2}{3} - \frac{2}{8} - (2 + \frac{11}{15}$

$\frac{2}{3} - \frac{2}{8} - \frac{41}{15}$

$- \frac{139}{60}$

C)

$\frac{1}{2} + ( \frac{1}{5} + \frac{1}{3} )$

$\frac{1}{2} + \frac{8}{15}$

$\frac{31}{30}$
