Rates are used to compare related quantities such as costs of items in two countries
The question is incomplete;
So, I will give a general explanation on how to calculate the rate.
Assume that the costs are:
United Kingdom = 500
Canada = 750
The ratio would be:
Ratio = United Kingdom : Canada
So, we have:
Ratio = 500 : 750
Simplify
Ratio = 2 : 3
Express as rate
Rate = 2/3
Using the assumed values, the rate of the total cost for items in the United Kingdom to that of the total cost of items in Canada is 2/3
