Comparing Fractions With Unlike Denominators Worksheet

Comparing Fractions With Unlike Denominators Worksheet

Fractions are a fundamental concept in mathematics, representing parts of a whole or ratios between quantities. When fractions have unlike denominators, comparing them can be a bit tricky for students. However, with the right approach and practice, mastering this skill becomes attainable. In this article, we provide a comprehensive guide and a sample worksheet for comparing fractions with unlike denominators, helping students build confidence and proficiency in this essential mathematical skill.

Understanding Fractions with Unlike Denominators

Before diving into comparing fractions with unlike denominators, it’s crucial to understand the basics:

Numerator: The numerator represents the number of equal parts being considered.
Denominator: The denominator indicates the total number of equal parts that make up a whole.

When fractions have different denominators, they represent different-sized parts, making direct comparison challenging. However, by finding a common denominator, we can make the fractions comparable.

Finding a Common Denominator

To compare fractions with unlike denominators, follow these steps to find a common denominator:

  • Identify the Denominators: Determine the denominators of the fractions you’re comparing.
  • Find the Least Common Multiple (LCM): Find the least common multiple of the denominators. This is the smallest number that is divisible by both denominators.
  • Create Equivalent Fractions: Rewrite each fraction using the common denominator.
  • Compare Numerators: Once the fractions have the same denominator, compare their numerators.
  • Sample Worksheet: Comparing Fractions with Unlike Denominators


For each pair of fractions, find a common denominator and then compare the fractions. Circle the greater fraction.

3/5 vs. 1/4
7/8 vs. 2/3
5/6 vs. 4/9
2/7 vs. 3/10
4/11 vs. 5/12

Answer Key:

3/5 > 1/4
7/8 > 2/3
5/6 > 4/9
2/7 < 3/10
4/11 < 5/12
