Ordering Fractions Use the LCM to find a common denominator.
BAIP Instructional Support Version 2 4/20/2017 Ordering Fractions Use the LCM to find a common denominator. Find equivalent fractions using the common denominator. List the new fractions from least to greatest. List the original fractions from least to greatest. 14

Order these fractions from least to greatest:
7/9 5/6 2/3 1/2

7/9 = 14/18 5/6 = 15/18 2/3 = 12/18 ½ = 9/18 Ordered from least to greatest: 9/18 12/18 14/18 15/18

Original fractions ordered from least to greatest:
1/2, 2/3, 7/9, 5/6

What fraction is greater than ¾?
7/12 5/8 2/3 7/9
