What is a mixed number?

A mixed number is defined as a whole number combined with a proper fraction. This format represents values that are greater than one but less than the next whole number, effectively allowing for a clear expression of whole parts and fractional parts together. For example, the mixed number 2 1/4 consists of the whole number 2 and the proper fraction 1/4, indicating that it is 2 whole units plus an additional quarter.

Other types of fractions or numbers mentioned in the other options do not fit this definition. A fraction with a numerator larger than the denominator describes an improper fraction, and a simple fraction refers to any fraction without the need for a whole number component. A decimal number conveys values differently, often in a base-10 format, which is distinct from how mixed numbers are structured. Therefore, the option highlighting the combination of a whole number and a proper fraction accurately captures the essence of a mixed number.
