Question

The ratio of people to pizzas for a party is 13/3. How many people will be served if Deb is using 30 pizzas?

Answer 1

130 people

Explanation:

This is a classic ratio problem that can be solved through dimensional analysis (the use of units and a little bit of thinking). If the ratio of people to pizzas for a party is 13/3, or in otherwords, for every 13 people there exists 3 pizzas, then if you have 30 pizzas, there will be 130 people, because

30 pizzas · 13/3 (peoples per pizzas)=130 people

Answer 2

The Answer is 130 people
