A part of a whole expressed as a numerator over a denominator.

A part of a whole expressed as a numerator over a denominator.

• A. Average
• B. Radius
• C. Fraction
• D. Exponent

Answer: (C)

Fractions express part of a whole, written with a numerator over a denominator. The numerator shows how many parts you have, and the denominator shows into how many equal parts the whole is divided. For example, 3/4 means you have three of the four equal parts. This description matches the statement in the question. The other ideas refer to different concepts: an average is a measure of central tendency in data, a radius is the distance from the center to the edge of a circle, and an exponent indicates repeated multiplication. These do not describe a part of a whole expressed as a numerator over a denominator, so they don’t fit as well.
