Question 468961
If x men working together at the same rate can complete a job in h hours, what part of the same job can one man working alone complete in k hours?
---
amt of job per hour for x men =  1/h
---
amt of job per man per hour for x men = (1/h)/x = 1/xh 
----
amt of job per man per k hours: k(1/xh) = k/(xh)
