A common size for a driveway in a suburban village is 80 feet long by 25 feet wide. Does a larger driveway that is 96 feet long by 30 feet wide have the same ratio of width to​ length?

Are the ratios​ proportional?

Answer 1

To determine if the larger driveway has the same ratio of width to length as the common size driveway, we can calculate the ratio for both driveways.

Common size driveway:
Width: 25 feet
Length: 80 feet
Ratio of width to length: 25/80 or 1/3.2

Larger driveway:
Width: 30 feet
Length: 96 feet
Ratio of width to length: 30/96 or 1/3.2

Since the ratio of width to length for both driveways is 1/3.2, they have the same ratio and are proportional.
