Question

bags of pancake mix cost $10 each.

each bag makes 120 pancakes.

each person will be served 3 pancakes.

 

Answer 1

240 persons · 3 pancakes / person = 720 pancakes

720 pancakes · 1 bag / 120 pancakes = 6 bags

Answer 2

You are given several pieces of information, but the question asks how many pancakes will the students need to serve 240 people.

 

We know that 1 person gets 3 pancakes.  We only need to use this piece of information to answer the question.

 

We can set a proportion.

 

Ratio of people = ratio of pancakes.

 

240 / 1 = x / 3

 

 

x is the number of pancakes that will serve 240 people.

 

 

Cross multiply.

 

x = 3 * 240

x = 720

 

The students will need to make 720 pancakes.
