Question

Calculati in doua moduri:
$( - \frac{3}{4} ) \times ( - \frac{5}{6} + \frac{2}{3} )$

Answer 1

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

$2) \\ \\ ( - \frac{3}{4}) \times ( - \frac{5}{6} + \frac{2}{3}) = - \frac{3}{4} \times \frac{ - 1}{6} = - \frac{ - 3}{4 \times 6} = - \frac{ - 3}{24} = - ( - \frac{3}{24}) = - ( - \frac{1}{8}) = \frac{1}{8}$
