Which of the following pairs represent the same rational numbers:
$\frac{-16}{20}and\frac{20}{-25}$

Answer 1

$\frac{-16}{20}and\frac{20}{-25}$
$\Rightarrow \frac{-16}{20}=\frac{-4}{5}and\frac{20}{-25}=\frac{4}{-5}=\frac{-4}{5}$ [Converting into lowest term]
$\because \frac{-4}{5}=\frac{-4}{5}\because \frac{-16}{20}=\frac{20}{25}$
