If it takes 12 teenagers to eat one pizza in 20 minutes, they spent 12 x 20 = 240 teenager-minutes chewing.

So, how many teenagers will it take to eat that pizza in 18 minutes?

Divide the number of teenager-minutes by minutes to get the number of teenagers.

240 teenager-minutes / 18 minutes = 13 1/3 teenagers.
