If Sam can do a job in 4 days that Lisa can do in 6 days and Tom can do in 2 days,
how long would the job take if Sam, Lisa, and Tom worked together to complete it?
What equation do you need to find the answer?

Let x = time required when working together
Let the completed job = 1
:
The equation
t%2F4 + t%2F6 + t%2F2 = 1
