Question

Write $\frac{2}{-5}$with a positive denominator.

Answer 1

Given,$\frac{2}{-5}$

We have to make the denominator positive.

For this, we multiply its numerator and denominator by $-1$to get an equivalent rational number with a positive denominator.

Thus,

$\frac{2}{-5}=\frac{2\times (-1)}{-5\times (-1)}=\frac{-2}{5}$

Hence, the required rational number with a positive denominator is $\frac{-2}{5}$
