-5 is the answer

-20a divided by 4a is -5.

If we times 4a by a positive number, we would get a positive number, so we have to times it by a negative number. The number can't have an a at the end as this would mean when we times it by 4a we would end up with a2

-5 x 4 = -20

then we add on the a = -20a
