Answer:
6 race cars
Explanation:
In this scenario, there would be a total of 6 race cars on the scale. Since each racecar weighs 1/4 pound then 4 racecars would equal 1. This leaves us with 1/2 or 0.5 pounds left. This would be 2 race cars since 2/4 is equal to 0.5 pounds. Therefore, if we add these two amounts up it would be a total of 6 racecars (4+2) which would total 1 1/2 pounds.
