1 2.1 Ordering Rational Numbers from Least to Greatest

2 Comparing Rational Numbers Using a Number Line Turn all rational numbers to either fractions or decimals Graph the rational numbers on the number line The number to the left is the smaller number

3

4 Comparing Decimals Compare place values from left to right Example:

5 Comparing Fractions Get the same denominator (LCD) – Find the LCM of the denominators Make an Equivalent fraction – Multiply each the fraction (numerator and denominator) by number to make the LCM Once the denominators are the same compare the numerators

6 Compare Using or =
