Which rational number is bigger than the rational number $\frac{0}{-8}$?

First evaluate the given value:
$$\frac{0}{-8}=0$$
Now check the options to find a value greater than 0:A) $-\frac{1}{2}=-0.5$ (less than 0)B) $\frac{-3}{-8}=\frac{3}{8}=0.375$ (greater than 0)C) $-\frac{8}{5}=-1.6$ (less than 0)D) $-\frac{1}{5}=-0.2$ (less than 0)Therefore, $\frac{-3}{-8}$ is the only value greater than 0.
