PLZ HELP liams parents are driving three times as fast as liam is biking, but they left later they he did. if his parents caught up with him two hours after he left, how much later than liam did he leave?

Hello.

The answer is 12/20. Even though it is a smaller fraction, it is not in simplest terms yet. A number that goes into both is 2. Divide numerator and denominator by 2 to get 6/10. But it is still not in simplest terms. 2 again goes into both numbers. Divide numerator/denominator by 2 to get 3/5. This is the simplest terms, and is greater than 5/8.
