Answer:
100
Step-by-step explanation:
The fraction 2/3 says there are 3 total parts to the track, but Pete only rode 2 of them.
In this type of problem you always multiply the amount of the whole (150) times the fraction of the whole you are calculating (2/3) to get the answer.
150*2 = 300 divided by 3 = 100
Or 150 * (2/3) = 150 * 0.66667 = 100
