Work Step by Step
Recall, when we are simplifying a fraction, we do addition and subtraction in the numerator and denominator before we divide. Thus, we obtain:
$ -12 \div -3$
In this problem, we are dividing two negative numbers. Remember, when we divide two negative numbers, the negatives cancel out, meaning that our answer will be positive. Thus, we find:
$-12 \div -3=4$
