  1. Ordering Rational & Irrational Numbers

  2. Ordering Rational & Irrational Numbers When ordering a group of rational & irrational numbers, 1.) change each number to its decimal format 2.) place the decimals in order 3.) convert their decimal back to their original rational or irrational form.

  3. Example 1 Order the following numbers from least to greatest. -4.5, - ½, √7, 3 -4.5 = -4.5 -4.5, -0.5, 2.65…, 3.6, -½ = -0.5 √7 = 2.65… -4.5, - ½ , √7, 3 3 = 3.6 2 3 2 3 2 3

  4. Example 2 Order the following numbers from least to greatest. √20, -2 , , 3.9 √20 = 4.472… -2.3, 3.3, 3.9, 4.472… -2 = -2.3 = 3.3 -2 , , 3.9, √20 3.9 = 3.9 1 10 3 3 1 3 10 1 10 3 3 3
