162/9 = 18 water bottles per case or
18:1
** The unit rate of bottles per case is given by:**
R = 18 ; To find the unit rate, we must follow the following procedure:
Divide the total number of water bottles into case numbers.
We have then:
R = 9 162
Rewriting the unit rate we have:
R = 18
The unit rate of water bottles per case is 18. This means that each case contains 18 water bottles. To find this, we divided the total number of water bottles by the number of cases.
