You can write numbers, $q$ $q$ 's and $r$ $r$ ''s apart

$= - \frac{6}{2} \times \frac{q}{q^{5}} \times \frac{r^{3}}{r}$ $=-6/2xxq/q^5xxr^3/r$

Then split up the powers of $q$ $q$ and $r$ $r$
$=-3xx(cancelq)/(cancelqxxq^4)xx(cancelrxxr^2)/cancelr$

$=-(3r^2)/q^4$

How do you simplify (6qr^3)/(-2q^5r)6qr3−2q5r(6qr^3)/(-2q^5r)?
