Final answer:
The average miles per gallon for the car, represented as a simplified fraction, is 36/7. This is found by dividing 72 miles by 14 gallons.
Step-by-step explanation:
To calculate the average miles per gallon (mpg) of gas for the car, we need to divide the total miles traveled by the total gallons of gas used. In this case, the car gets an average of 72 miles for 14 gallons of gas. To find the mpg, we use the following calculation:
MPG = Total Miles Driven / Total Gallons Used = 72 miles / 14 gallons
Simplifying this fraction, we get:
MPG = 72 / 14 = 5.14 (rounded to two decimal places)
Therefore, the simplified fraction representing the average miles per gallon is 72/14, which can be further reduced to 36/7.
