Question

Simplify.

$\frac{2}{-7}\times \frac{63}{-100}$

Answer 1

First , we write the rational numbers in their standard form.

$\frac{2}{-7}\times \frac{-1}{-1}=\frac{-2}{7}$

and $\frac{63}{-100}\times \frac{-1}{-1}=\frac{-63}{100}$

$\therefore \frac{2}{-7}\times \frac{63}{-100}=\frac{-2}{7}\times \frac{-63}{100}=\frac{-2\times -63}{7\times 100}=\frac{-1\times -9}{1\times 50}=\frac{9}{50}$

Hence , $\frac{2}{-7}\times \frac{63}{-100}=\frac{9}{50}.$
