Mathmatical Reflection 1 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. ****1.**Give another example of each type of comparison.
 * The Big Idea:**
 * Investigation 1:** Making Comparisons
 * Essential Question:** ** What methods are there for comparing things?

Ratios A another example of this is 7 boys to 8 girls in my class. Differences There are 25 boys in my grade and 20 girls in my grade, the difference is the boys outnumber the girls by 5 people. Fractions 25/20, 25 boys and 20 girls in our grade. Percents 44% of 7th grade are girls and the other 46% are boys. Scaling There is 1.25 times the boys to the girls.

In a difference you get one number as the answer and a ratio you compare two numbers, which a difference doesn't have.
 * 2.**What in do you get from a ratio comparison that you don't get from a difference comparison?

In this chapter I learned about all different ways to compare, Differences, of course Ratios, Fractions, Percents, and Scaling. Now I understand them more clearly. In this MR I showed what I learned.
