Question

3/4(-5/6+7/8)=(3/4+-5/6)+7/8​

Answer 1

Answer:

$\frac{3}{4} ( \frac{-5}{6} + \frac{7}{8} ) = ( \frac{3}{4} + -\frac{5}{6} + \frac{7}{8} ) \\ \\ = \frac{3}{4} ( \frac{-40 + 42}{48}) = \frac{3}{4} - \frac{5}{6} + \frac{7}{8} \\ = \frac{3}{4} \times \frac{2} {48} = \frac{18 - 20}{24} + \frac{7}{8} \\ = \frac{6}{192} = - \frac{2}{24} + \frac{7}{8} \\ = \frac{6}{192} = - \frac{ - 16 + 168}{192} \\ = \frac{6}{192} = \frac{152}{192}$
