What type of fraction has a denominator that is greater than its numerator?

A proper fraction is defined specifically by having a numerator that is less than its denominator. This means that in a proper fraction, the value of the fraction is less than one. For example, in the fraction 3/4, the numerator (3) is less than the denominator (4), thus it is considered a proper fraction.

In contrast, an improper fraction has a numerator that is greater than or equal to its denominator, resulting in a value that is one or greater. A mixed number combines a whole number with a proper fraction, and equivalent fractions represent different fractions that have the same value. Therefore, the defining characteristic of a proper fraction being one where the numerator is lesser than the denominator sets it apart from the other types of fractions listed.
