Skill: Compare fractions with the same numerator

Explanation and Free Practice Resources

When positive fractions have the same numerator, the denominator determines their relative size: counting the same number of parts, a larger denominator creates smaller equal parts, so the fraction is smaller. Number lines and area models make this inverse relationship visible and correct the misconception that a larger denominator always makes a fraction larger; comparison here is limited to common numerators and does not include general methods for comparing fractions with unlike numerators.

Detailed Explanation: Compare fractions with the same numerator

When two positive fractions have the same numerator, compare their denominators.

The denominator tells how many equal parts the whole is divided into:

  • A larger denominator makes smaller parts.
  • Counting the same number of smaller parts gives a smaller fraction.

Example: Compare 34\frac{3}{4} and 38\frac{3}{8}

  1. The numerators are the same: both are 33.
  2. Compare the denominators: 88 is greater than 44.
  3. Eighths are smaller pieces than fourths. So 33 eighths is less than 33 fourths.
  4. Write the comparison:
38<34\frac{3}{8}<\frac{3}{4}

On a number line, 38\frac{3}{8} is closer to 00, while 34\frac{3}{4} is farther to the right. Remember: with the same numerator, the fraction with the larger denominator is smaller.
