Rational Numbers 101: Understanding the Definition and Importance - legacy

At its core, a rational number is a type of number that can be expressed as the ratio of two integers, with the numerator and denominator being whole numbers. Rational numbers are often represented as a fraction, with a finite decimal expansion. For example, 3/4 and 0.75 are both rational numbers. This simple yet powerful definition makes rational numbers fundamental to our understanding of mathematics, as they can be used to represent a wide range of quantities and operations.
