Big Idea : Many important practical and mathematical applications involve comparing quantities of one kind or another; it is important to know which method to use and how we should use them.  __Essential Question:__ //What methods are there for comparing things?

Notes from class:

2/3 = 80/120 1/4 = 30/120

4/8 = 60/120 3/5 = 72/120

A. Which recipe will make juice that is the most "orangey"? Explain your answer.

Mix A would make the most orangey because it has the more concentrate than the water between different mix.//

B. Which recipe will make the juice the least "orangey"? Explain your answer.

Mix B would make the least orangey because it has the least concentrate mixed with water than the other mix.

C. Assume that each camper will get 1/2 cup of juice. For each recipe, how much concentrate and water are needed to make juice for 240 campers? Explain your answer.

Mix A Mix B Mix C Mix D C: 48 C: 24 C:40 C:45 W:72 W: 96 W:80 W:75

Follow - up

1. How did you use ratios in solving Problem 3.1? In 3.1 A and B I used ratios to compare the concentrates. In question letter C. I used comparison to see the difference in amount of concentrates and water.

2. For each recipe, how much concentrate and how much water is needed to make 1 cup of juice?
