You can put this solution on YOUR website!
The cabinet maker's rate of working is:
( 3 cabinets ) / ( 2 days )
-----------------------
If the apprentice works at half that rate,
his rate is:
( 3 cabinets ) / ( 4 days )
---------------------
How long will it take the apprentice to make
3 times as many cabinets?
It will takes 3 times as long, or +3%2A4+=+12+
12 days
---------
In terms of just units,
( number of cabinets ) / ( rate in cabinets/days ) = days
+9+%2F+%28+3%2F4%29+=+12+
