ANSWER-》》

5(i)Solution.

$\frac{4 }{13} \times \frac{ - 7}{11} = \frac{ - 7}{11} \times \frac{4}{13} \\ \frac{ - 28}{143}$
Cumulative Property of multiplication for whole numbers is inserted.

5(ii)Solution.

$\frac{ - 7}{8} \times ( \frac{2}{9} \times \frac{3}{5} ) = ( \frac{ - 7}{8} \times \frac{2}{9} ) \times \frac{3}{5} \\ \frac{7}{60}$
Associative Property of multiplication is inserted.

5(iii)Solution.

$\frac{3}{11} \times ( \frac{2}{5} + \frac{1}{2} = \frac{3}{11} \times \frac{2}{5} + \frac{3}{11} \times \frac{1}{2} \\ = \frac{270}{110}$

5(iv)Solution.

$\frac{4}{15} \times ( \frac{5}{6} - \frac{2}{3} )\\ = \frac{4}{5} \times \frac{5}{6} - \frac{4}{15} \times \frac{2}{3} \\ = \frac{2}{15}$
