If 12 men do a piece of work in 80 days. In how many days will 16 men do it?
---------------
# of days and # of men are inversely related:
d = k/m
---
solve for "k" using "12 men do a piece of work in 80 days"::
80 = k/12
k = 960
----
Equation:
d = 960/m
-----
In how many days will 16 men do it?
d = 960/16
# of days = 60
----------
