The correct answer is a fraction. A fraction represents a part of a whole and is expressed as a ratio of two numbers, typically written in the form of one number over another (e.g., 1/2, where 1 is the numerator and 2 is the denominator). This indicates how many parts of a certain size are present. In contrast, area refers to the measurement of a surface, denoting the amount of space within a two-dimensional shape. The denominator specifically relates to the bottom number in a fraction that indicates into how many equal parts the whole is divided, but it does not itself represent a part. Volume measures the amount of space that a three-dimensional object occupies, which is separate from the concept of a part of a whole. Understanding these terms helps clarify that a fraction directly embodies the idea of a small part forming part of a whole.
