Fractions with a common positive denominator name equal-sized parts of a whole, so their order is determined by comparing their numerators: the fraction with more parts is greater, and equal numerators represent equal quantities. This understanding applies to proper and improper fractions within familiar whole-number ranges, supports locating and ordering fractions on a number line, and distinguishes denominator size from the amount represented; comparing unlike denominators is not included.
When two fractions have the same positive denominator, they are divided into the same number of equal-sized parts. Compare the numerators to see how many parts each fraction has.
Example: Compare and .
Check the denominators: both are .
This means the fractions name equal-sized parts.
Compare the numerators: and .
Since , represents more parts than .
Therefore,
Remember: when the denominators are the same, the fraction with the greater numerator is greater.
