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.

### Instructions:

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
