Ratios and Proportions

We reviewed the chapter 9 tests, and then began our study of chapter 11. The first section deals with ratios and proportions, so I reviewed how to use cross-products to solve algebraic problems. Be sure to read Lesson 11.1, especially if you missed class on Wednesday.

Tonight's homework: Lesson 11.1 ( 17 - 38, first column only, and problems 41 and 42)
