162 water bottles in 9 cases = ?

Question

Must be writen as a unit rate

Answer 1

Elizabeth,

The unit rate for this problem would be the number of bottles in 1 case. This can be determined by:

162 bottles = x bottles

9 cases = 1 case

Divide the numerator ad denominator by 9:

162 bottles ÷ 9 = x bottles

9 cases ÷ 9 = 1 case

x = 18 bottles

The unit rate would be:

18 bottles

1 case
