Objective 12 Order real numbers © 2002 by R. Villar All Rights Reserved Order real numbers Real Numbers: all positive numbers, all negative numbers, and zero. (Everything on the number line). Example: Plot the following points on the number line… 4 3 , π , 6.25 , –5 , 9 Convert all of these to decimals to make it simple to compare. Then place them on the number line... 3.14 , 6.25 , 5 , 1.73 , 0.44 Example: Place the following numbers in the correct order... π , 9.4 , –9.7 , 2 Convert all of these to decimals to make it simple to compare. Then place them in order using inequalities... 3.14 , 9.4 , 9.7 , 1.41 By looking at the number line, the correct order is as follows: 9.7 2 9.4
