Chapter 1: Q.420 (page 92)

In the following exercise,Perform the indicated operation, $\frac{\frac{- 4}{9}}{\frac{8}{21}}$

Short Answer

Expert verified

The simplified value of the expression is $\frac{- 7}{6}$

Step by step solution

Step 1. Given information

The given expression is $\frac{\frac{- 4}{9}}{\frac{8}{21}}$

Step 2. Perform division operation

if $a, b, c, d$ are numbers then $\frac{a}{b} \div \frac{c}{d} = \frac{a}{b} \times \frac{d}{c}$

$\frac{\frac{- 4}{9}}{\frac{8}{21}} = \frac{- 4}{9} \times \frac{21}{8} = \frac{- 1}{3} \times \frac{7}{2} = \frac{- 7}{6}$

Step 3. Conclusion

Hence, the value of the given expression is $\frac{- 7}{6}$
