Question

Given below is a positive rational number or not?
$\frac{3}{-5}$

Answer 1

$\frac{3}{-5}$ can also be written as $\frac{(3\times (-1\left)\right)}{(-5\times (-1\left)\right)}=-\frac{3}{5}$

So, this is rational number, but not positive.

Hence, $\frac{3}{-5}$ is not a positive rational number.
