An example of a ratio is Dollars:Miles.
The unit rate is helpful when reasoning about ratios.
Write the first ratio that is given as a fraction:
6miles$4
Reduce it to simplest form:
6miles÷4$4÷4=1.5miles$1
Use the simplified fraction to set up a proportion to solve for the missing value:
1.5miles×64$1×64=96miles$64
Use inverse operations:
96÷1.5=64
Therefore, the cost of gas that will be used to drive the bus for 96 miles is $64.
