Question

solve this question please who give all the answer i will mark in brainliest and solve step by step

Answer 1

1. R.H.S

$- \frac{ 7}{8} \times (\frac{4}{21} \times - \frac{3}{4}) \\ - \frac{7}{8} \times - \frac{1}{7} \\ \frac{1}{8}$

L.H.S

$(- \frac{7}{8} \times \frac{4}{21} ) \times - \frac{3}{4} \\ ( - \frac{ 1}{6} ) \times - \frac{3}{4} \\ \frac{1}{8}$

2. i,

$- \frac{ 3}{4} \times ( - \frac{5}{6} \times \frac{7}{8} ) \\ - \frac{ 3}{4} \times - \frac{ 35}{48} \\ \frac{105}{192}$

ii,

$- \frac{2}{3} \times ( \frac{7}{9} \times - \frac{8}{5} ) \\ - \frac{2}{3} \times - \frac{56}{45} \\ \frac{112}{135}$
