Answer: The two unit rates are 1 to 3 or 3 to 1.

A unit rate is a rate in which one of the rates is equal to 1.

In the case of our rates, we have decimals and not the number one. So we have to convert the fractions.

1.5/0.5 = 15/5 = 1/3

Our fraction simplifies to the unit rate of 1/3 or we can flip it to create 3/1.
