There are 3 pizzas left over. Each person will eat 2/8 of a pizza. How many people will 3 pizzas feed?

3 pizzas / (2/8 pizza/person)=

3 x 8/2 people = 12 people

one person: \(\frac{2}{8}\) of a pizza, or \(\frac{1}{4}\) of a pizza.

Since we have \(3\) pizzas, there will be \(\frac{3}{\frac{1}{4}}=3*4=\boxed{12}\) people.
