Students will determine if given fractions are less than, equal to, or greater than 1. Students who are successful at this have already generalized the rule: fractions greater than 1 have numerators larger than their denominators; those that are less than 1 have numerators smaller than their denominators; the rest are equal to 1.
If students found this activity hard, you may want them to go over the finished lists and try to articulate the rule. How To Compare: Convert each fraction to an equivalent fraction with a common denominator. How To Compare: Look at the denominators. Summary: In this lesson, we learned how to compare fractions with like denominators, with unlike denominators, and with like numerators. To compare fractions with unlike denominators, use the LCD to write equivalent fractions with a common denominator; then compare the numerators.

These fractions have like denominators, so we can compare the numerators. Josephine: Penelope: Solution: Since nine-twelfths is greater than eight-twelfths, three-fourths is greater than two-thirds.
Josephine: Penelope: Procedure: To compare fractions with unlike denominators, follow these steps: 1. Use the LCD to write equivalent fractions with a common denominator. Compare the numerators: The larger fraction is the one with the greater numerator. Let's look at some more examples of comparing fractions with unlike denominators.
Example 4: Analysis: Convert these fractions to equivalent fractions with a common denominator in order to compare them. Step1: Find the least common multiple LCM of 8 and The LCM of 8 and 10 is Analysis: Step 2: Convert each fraction to an equivalent fraction with a denominator of Answer: Example 5: Analysis: Convert these fractions to equivalent fractions with a common denominator in order to compare them. Step 1: Find the least common multiple LCM of 6 and 4. The LCM of 6 and 4 is Answer: Example 6: Analysis: Convert these fractions to equivalent fractions with a common denominator in order to compare them.
Step 1: Find the least common multiple LCM of 9 and 3. Analysis: Step 2: Convert each fraction to an equivalent fraction with a denominator of 9. Answer: In this lesson, we have compared fractions with like denominators and with unlike denominators.
Keep on reading to find out! So, how do you do it? And it seems like we do all of this pretty much automatically without really thinking about it. Which means we have to do a bit of work. Method 1: Use a Common Denominator And that brings us to our first method for comparing fractions: writing them in terms of a common denominator. Once two or more fractions are rewritten in terms of a common denominator, all you have to do to compare them is look at their numerators.
