Which of the following describes a mixed number?

A mixed number is indeed described as an integer combined with a fraction. This means it consists of a whole number part and a fractional part, such as 2 1/2, which reflects both a complete unit (the integer 2) and an additional part of a unit (the fraction 1/2).

Understanding mixed numbers is essential in various mathematical contexts, including addition, subtraction, and real-world applications like measuring and cooking, where quantities are often expressed this way for convenience. The presence of both an integer and a fraction allows for the representation of values that are greater than one but not whole integers, facilitating a more nuanced understanding of numerical relationships and operations.
