Write two division problems related to the multiplication problem below. 8×(-2)=-16
Alenkasestr [34]

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!
