Noreen 3 1/3 hours on her math project. Donald worked 1 1/5 times as long on his math project as Noreen did.For how many hours did Donald work on his math project?
Answer provided by our tutors
3 1/3 = (3*3 + 1)/3 = 10/3 hours is the time that Noreen worked
1 1/5 = (1*5 + 1)/5 = 6/5 times Donald worked more
(6/5)*(10/3) = 4 hours
Donald worked 4 hours on his math project.
