Signs change when you multiply by a negative number -- but do not change when you multiply by a positive number.
Division is just multiplication by the inverse -- so the same rules apply.
You do not change the sign when you divide by five. But you would change it is you divided by (-5).

The sign only changes when you divide by a negative number. Therefore when dividing by 5, the sign will not change, but when dividing by -5, it will.

I believe Megan is right.
You only need to change signs when dividing by a negative number.

The sign does not change as long as what you do to the right side you also do the the left side.
