Question

Question 6 (vii)
Is the given pair represent the same rational number ?
$\frac{-5}{-9}and\frac{5}{-9}$

Answer 1

$\frac{-5}{-9}and\frac{5}{-9}$
$\Rightarrow \frac{-5}{-9}=\frac{5}{9}and\frac{5}{-9}=\frac{5}{-9}$ [Coverting into lowest term]
$\because \frac{5}{9}\ne \frac{5}{-9}\therefore \frac{-5}{-9}\ne \frac{5}{-9}$

The given pair does not represent the same rational number.
