Yep. Since one teenager can eat a pizza a day, then 12 teens should be able to eat 36 pizzas in 3 days.

The answer is 24.
You can set the problem up as fractions.
1.5 teens/1.5 pizzas = 1.5 days
the teens to pizza are 1:1. So you would say 1/1=1.5
then change it to 12/12 = 1.5 and you would multiple by 2 to get 3 days.
so 12*2 = 24

I am a pharmacist and the correct way to solve questions like this is think of RATE OF CONSUMPTION.
i.e. consumption = pizza/day
i.e. 1.5 TEENS = 1.5 PIZZA/1.5DAY = 1 pizza/day
the rest is simple maths.
