  6. Introduction to Ratios Definition of Ratio: Shows the relative size of two or more values Ratios can be represented in three ways: • Part to Part stars to circles 3:4 • Part to Whole stars to shapes 3:7 • Whole to Part shapes to circles 7:4 Part- describes a portion or part of the picture Whole - describes the whole picture • Ratios can be written in three ways: • Using a colon • Example 3 : 4, 3 : 7, 7 : 4 • Using the word “to” • Example 3 to 4, 3 to 7, 7 to 4 3) As a fraction (only part to whole ratios can be written like this) Example: 3/7

  7. Practice with Equivalent Ratios Reduce the following ratios: 1) 2:4 2) 6:9 3) 5:15 4) 12:20 5) 18:45 6) 21:49 7) 30:72 8) 39:52

  8. Ratio – A ratio is a comparison between two or more quantities that are related. • Ratios can beequivalentto each other in the same way that fractions can be. • Example • Girls to Boys 3:2 Is equivalent to the ratio of girls to boys 6: 4
