3 men build a wall in 4 days
--------------------------
1 man will take three times as long
to build the wall, so
--------------------
1 man can build the wall in 12 days
--------------------------------
5 times as many men will take 1/5 of that
time to build the wall, so
-------------------------
5 men can build the wall in +12%2F5+=+2.4+ days
