M L Aggarwal Solutions for Chapter: Rational Numbers, Exercise 1: Exercise

Find the multiplicative inverse of $\frac{-3}{8}\times \left(\frac{-7}{13}\right)$

Using the appropriate properties of operations of rational numbers, evaluate the following:

$\frac{2}{5}\times \frac{-3}{7}-\frac{1}{14}-\frac{3}{7}\times \frac{3}{5}$

Using the appropriate properties of operations of rational numbers, evaluate the following: $\frac{8}{9}\times \frac{4}{5}+\frac{5}{6}-\frac{9}{5}\times \frac{8}{9}$

Using the appropriate properties of operations of rational numbers, evaluate the following: $\frac{-3}{7}\times \frac{14}{15}\times \frac{7}{12}\times \left(\frac{-30}{35}\right)$

Using distributivity, find $\left\{\frac{7}{5}\times \left(\frac{-3}{12}\right)\right\}+\left\{\frac{7}{5}\times \frac{5}{12}\right\}$

Using distributivity, find $\left\{\frac{9}{16}\times \frac{4}{12}\right\}+\left\{\frac{9}{16}\times \left(\frac{-3}{9}\right)\right\}$
