Comparing Fractions

NUMERATOR DENOMINATOR

To compare two fractions (that is, to find out which one is bigger or smaller):

1. Write the fractions so that they have the same denominator (if they already have the same denominator, skip this and go to the last step). To make each fraction have the same denimonator:
   • Find the least common multiple (LCM) of the denominators (it is 12 in the example to the right).
   • Multiple each fraction by n/n, where n is the number that, when multipled by the denominator, results in the LCM (in the example to the right, n/n is 3/3 for the first fraction and 4/4 for the second fraction).
2. Compare the numerators; the fraction with the largest positive numerator is the larger fraction.

Comparing Fractions Worksheets:

LCM, GCD Factor two numbers into primes, then use a Venn diagram to compute their Least Common Multiple (LCM) and Greatest Common Divisor (GCD). Or go to an example of how to use this diagram.

Comparing Fractions Compare the pairs of fractions, determining which is larger. Worksheet #1 (same denominators) --- Go to the answers. Worksheet #2 (different denominators) --- Go to the answers. Worksheet #3 (different denominators) --- Go to the answers.
