To solve this problem, we must remember that division is the inverse operation of multiplication. This means to undo any multiplication problem, we can divide.
Because 8 * -2 = -16, if we divide the product by the two factors, we can reveal this unique relationship, as shown below:
-16/-2 = 8
-16/8 = -2
Therefore, the two division problems above are your answer.
Hope this helps!
