Question

verify that (-7/6×-2/5)×3/8=-7/6×(-2/5×3/8)​

Answer 1

$(- \frac{7}{6} \times - \frac{2}{5} ) \times \frac{3}{8} = - \frac{7}{6} \times ( - \frac{2}{5} \times \frac{3}{8} ) \\ lhs = > \\ ( - \frac { 7}{6} \times - \frac{2}{5} ) \times \frac{3}{8} \\ = \frac{14}{30} \times \frac{3}{8} \\ = \frac{7}{40} \\ rhs = > \\ - \frac{7}{6} \times ( - \frac{2}{5} \times \frac{3}{8} ) \\ = - \frac{7}{6} \times ( - \frac{6}{40} ) \\ = \frac{7}{40}$

Hence,LHS = RHS

proved.
