Practice makes perfect
To evaluate the given expression for r=12 and s=-4, first, we should substitute these values into the expression and simplify.

Same Sign & Different Signs
(+)÷(+)=(+) & (+)÷(-)=(-)
(-)÷(-)=(+) & (-)÷(+)=(-)
In our case one number is positive and one number is negative, so the quotient will be negative.
