Please help me solve this problem.If 6 men can do a piece of work in 14 days, how many men are needed to do the work in 21 days?
-----
# of days and # of men are inversely related.
---
m = k/d
----
Solve for "k" using "6 men can do a piece of work in 14 days".
6 = k/14
k = 6*14 = 84
------
Equation:
m = 84/d
---
Solve: How many men are needed to do the work in 21 days?
m = 84/21
m = 4
# of men needed is 4
