Twelve hungry teenagers can devour a very large pizza in 20 minutes. How many teenagers would it take to finish a very large pizza in 18 minutes? (Assume that all teenagers eat pizza at the same rate.)

Since twelve hungry teenagers can devour a very large pizza in 20 minutes, it takes 240 minutes (12 x 20) of chewing.

 

240 / 18  =  ...     number of teenagers  (you'll have to decide what to do with the fraction)
