CHAPTER 3 Ratio, Proportion, and Percent Lesson 1: Ratio and Proportion Key Ideas A ratio has two terms and can be written in words, with a colon, or as a fraction. Ratios are simplified by reducing to lowest terms. The terms in a ratio can have different labels. Ratio A ratio compares two numbers. You can write a ratio using the word to, using a colon (:), or using fraction form. Example 1: A softball pitcher strikes out four batters for every one batter that she walks.
