Which of the following best describes the fraction 4/3?

The fraction 4/3 is classified as an improper fraction because the numerator (4) is greater than the denominator (3). Improper fractions are defined as fractions where the numerator is equal to or larger than the denominator, which indicates that they represent a value equal to or greater than one whole. In this case, since 4 is greater than 3, 4/3 exceeds one whole, making it an improper fraction.

To provide some context: a proper fraction is defined as one where the numerator is less than the denominator, thus representing a value less than one. A mixed number consists of a whole number and a proper fraction, while a unit fraction has a numerator of one, representing a single part of a whole. These definitions help clarify why 4/3 is categorized appropriately as an improper fraction.
