A master can make 180 parts in 3 days, and his apprentice can make in 6 days. In how many days can a master and a student complete the entire task, working together?
the first step is to find out how many parts a master and an apprentice can make in 1 day: 180: 3 = 60 (master) and 180: 6 = 30 (apprentice)
60 + 30 = 90 (parts when working together in 1 day)
180: 90 = 2
