What is the quotient of 15p^-4 q^-6/-20p^-12 q^-3 in simplifed form?

In this question, you have two variable p and q. To simplify it, you need to divide each variable which will result in subtracting the power/exponent. Since all the exponent is a minus, it will be easier to switch the position first. The calculation should be:

15 * p^-4 * q^-6 / - 20 * p^-12 * q^-3=

15 * p^12 * q^3 / - 20 * p^4 * q^6=

15 / - 20 * p^ (12-4) * q^ (3-6) =

-3 / 4 * p^8 * q * - 3=

-3 * p^8 / q^3
