Santa's helpers

Santa Claus found that two elves could pack two stockings in two minutes. How many temporary elves did Santa Claus have to hire to get those stockings packed at the rate of eighteen stockings every six minutes? (from the book by A. Salny)

3elves (1per min)= 3stock/min

3stockx6 min +18 stock

2elves have packing rate of 2/2min

want to pack at rate of:
18/6min
reduce stockings packed/2min:
6/2min

numelfpairs(2 stocks/2min)= 6 stocks/2min

numelfpairs=3

6 elves

Great! New puzzle is coming tomorrow.
And it will not require any of the math symbols to be explained or solved :)
Check in the morning.
