Session 9: Fractions, Percents, and Ratios

In this session, we'll look at several topics related to fractions, percents, and ratios. As in earlier sessions, we'll look at graphical and geometric representations of these topics, as well as some of their applications in the physical world. As you work through the activities in this session, reflect on how mathematics is reasonable and logical, and how it is helpful to look for the logical patterns that emerge when you think about a mathematical situation.

For information on required and/or optional material, see Note 1
