A ratio shows us the number of times a number contains another number.

Naomi drove 14 miles in 16 minutes.

Ratio = 14/16 = 7/8

Noah drove 28 miles in 32 minutes.

Ratio = 28/32 = 7/8

Since the ratio is the same it is Proportional.

Naomi drove 13 miles in 18 minutes.

Ratio = 13/18

Noah drove 7 miles in 9 minutes.

Ratio = 7/9

Naomi drove 12 miles in 15 minutes.
