Question

4
$( \frac{4}{6} ) + ( \frac{ - 1}{2} )$
$( \frac{ - 2}{4} ) + ( \frac{ - 1}{8} )$
​

Answer 1

Explicação passo-a-passo:

$\frac{4}{6} + \frac{(-1)}{2}\\ \frac{4}{6} - \frac{1}{2}\\\frac{8 - 6}{12} = \frac{2}{12} = \frac{1}{6}\\\\\frac{(-2)}{4} + \frac{(-1)}{8}\\\\\frac{(-2)}{4} - \frac{(1)}{8}\\\frac{-16-4}{32} = \frac{-20}{32} = \frac{-5}{8}$
