Answer:
80 ÷ 16 = 5
Step-by-step explanation:
The "family facts" seem to be related to the relationship ...
5 × 16 = 80
One of the facts is generated from this one by reversing the order of the factors:
16 × 5 = 80
The other two are found by dividing the equation by one or the other of the factors:
16 = 80/5 . . . . . divide by 5
5 = 80/16 . . . . . divide by 16
This last one is the one that is missing. It the form used in the problem statement, it is ...
80 : 16 = 5
