4. Open Response The ratio of Braydon's
number of laps he ran to the time he ran is
6:2. The ratio of Monique's number of laps
she ran to the time she ran is 10: 4. Explain
why these ratios are not in a proportional
relationship. (Lesson 2)

Answer 1

(Some textbooks describe a proportional relationship by saying that " y varies proportionally with x " or that " y is directly proportional to x .") This means that as x increases, y increases and as x decreases, y decreases-and that the ratio between them always stays the same.

10:4 = 5:2

6:2 = 3:1

Not equal.
