ποΈ Quick Comparison Rules
- If the denominators are the same, the fraction with the larger numerator is greater.
- If the numerators are the same, the fraction with the smaller denominator is greater.
ποΈ Comparing Fractions Using a Common Denominator
- Find the lowest common multiple (LCM) of the denominators. For example, the LCM of 6 and 10 is 30.
- Convert both fractions to have this same denominator, then compare numerators.
ποΈ When One Denominator Is Already the LCM
- Sometimes one fraction already has the LCM as its denominator.
- Only change the other fraction, then compare the numerators.
ποΈ When Denominators Are Prime to Each Other
- If the denominators have no common factors, the LCM is their product.
- When the denominators are the same, you can ignore them and just compare the numerators.
Practice Questions

Which is greater, or ?
Correct! π +10 pointsNot quite right
Since both fractions have the same denominator, comparing the numerators tells us that is greater than .
Which is greater, or ?
Correct! π +10 pointsNot quite right
Since both fractions have the same numerator, the fraction with the smaller denominator represents a larger value, so is greater.
