3.1+Mixing+Juice

27-January-2009 **Essential Question: ** //__What methods are there for comparing things?__//
 * SF**
 * 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. 

**A. Which recipe will make juice that is the most “Orangey "? ** Mix A: - 2 cups concentrate 3 cups cold water because the difference between these two numbers ratio is really close.

Mix C: - 4 cups concentrate 8 cups of cold water because the difference between them is 4 and it is the most. This ratio is far apart from each other the most also.
 * B. Which recipe will make juice that is the least “Orangey "?**

For each you will need:- 72 cups of cold water 96 cups of cold water 80 cups of cold water 75 cups of cold water.
 * C. Assume that each camper will get half cup of juice. For each recipe, how much concentrate and how much water are needed to make juice for 240 campers?**
 * Mix A= 48 cups concentrate
 * Mix B= 24 cups of concentrate
 * Mix C= 40 cups of concentrate
 * Mix D= 45 cups concentrate

Well I used ratio to answer my questions because that is one of the forms of ratios.
 * Follow-up **
 * 1. How did you use ratio to solve problem 3.1? **

three fifths eight twelfths of cold water  <span style="font-family: "Times New Roman","serif";">*Mix B= one fifths cup of concentrate *Mix D= three eights cup of concentrate <span style="font-family: "Times New Roman","serif";"> Fourths of cold water five eights cup of cold water <span style="font-family: "Times New Roman","serif";">
 * 2. for each recipe, how much concentrate and how much water is needed to make 1 cup of juice?**
 * Mix A= tow fifths of concentrate *Mix C= four twelfths of concentrate
