Hello,

Can someone help explain the method to solve the following problem?

If Sam can do a job in 4 days that Bob can do in 6 days, and Tom can do it in 2 days, then how long would the job take if they all worked together?

I can get get close by using pictures and working through it that way, but I'm looking for the way to set it up in a formula.

Thanks for your help.
