Write the missing family
fact
5 x 16 = 80
80 : 5 = 16
16 x 5 = 80

  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
