A person-hour is a unit of measure representing one person working for one hour. A construction foreman estimates that it will t
ake 2880 person-hours to build a new library. If 12 workers are scheduled to work on the project at the same time how many hours will it take to complete the project?
If this fraction is closer to one it will be close to 16/16. And since 8 is half of 16, any fraction that is around 8/16 is closer to 1/2. 15 is closer 16 so this fraction is closer to one.
