Answer 1

Olá!

$\frac{ \frac{1}{3} + \frac{1}{2} }{ \frac{4}{8} - \frac{12}{8} } = \frac{ \frac{1}{3} + \frac{1}{2} }{ \frac{1}{2} - \frac{3}{2} } =\frac{ \frac{1}{3} + \frac{1}{2} }{ - \frac{1}{2}} = (\frac{1}{3} + \frac{1}{2}).( - \frac{1}{2}) = (\frac{2}{6} + \frac{3}{6}).( - \frac{1}{2}) = \frac{5}{6} .( - \frac{1}{2}) = - \frac{5}{12}$

Espero ter ajudado!
