For a complete lesson on comparing fractions, go to http://www.MathHelp.com - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students learn to compare fractions with the same denominator, which are called like fractions, by comparing the numerators. For example, to compare 7/9 and 4/9, note that 7 is greater than 4, so 7/9 is greater than 4/9. Students also learn to compare fractions with the different denominators, which are called unlike fractions, by first finding a common denominator, then comparing the numerators. For example, to compare 1/2 and 1/3, first find a common denominator, or the Least Common Multiple of 2 and 3, which is 6. To get 6 in the denominator of 1/2, multiply the numerator and denominator by 3, to get 3/6. To get 6 in the denominator of 1/3, multiply the numerator and denominator by 2, to get 2/6. Next, compare 3/6 and 2/6. Note that 3 is greater than 2, so 3/6 is greater than 2/6, which means that 1/2 is greater than 1/3.
