Which of the following option one or option two is proportional option one five six equals 15/8 or option two five six equals 20 over 18

Option one: 5/6 = 15/8

To check if the two ratios are proportional, we can cross multiply:

5 * 8 = 40
6 * 15 = 90

40 does not equal to 90, so the ratio 5/6 is not proportional to 15/8.

Option two: 5/6 = 20/18

Cross multiply to check proportionality:

5 * 18 = 90
6 * 20 = 120

90 does not equal to 120, so the ratio 5/6 is not proportional to 20/18 as well.

Therefore, neither option is proportional.
