A common size for a driveway in a suburban village is 75 feet long by 25 feet wide. Does a larger driveway that is 105 feet long by 40 feet wide have the same ratio of width to​ length?

Question

Are the ratios​ proportional?

Answer 1

To determine if the ratios of width to length are the same for both driveways, we need to calculate the ratios for each driveway.

For the first driveway (75 feet long by 25 feet wide):
Ratio of width to length = 25 / 75 = 1 / 3

For the second driveway (105 feet long by 40 feet wide):
Ratio of width to length = 40 / 105 = 8 / 21

These ratios are not the same, so the two driveways do not have the same ratio of width to length. Therefore, the ratios are not proportional.
