If Mario can do a piece of work in 3 days and Joey in 2 days, in how many days can they do the same work together?
--------------------------------
Realistically, about 7 days, since they'll waste time together.
Using math, tho:
M does 1/3 of the work per day.
J does 1/2 of the work per day.
Together, 1/3 + 1/2 = 5/6 of the work per day.
--> 6/5 days to do the work, or 1.2 days.
-----------------------------
Use the shortcut, product/sum
3*2/(3+2) = 6/5
