## Identifying Rational and Irrational Numbers

Rational numbers are numbers that can be expressed as a fraction, with a numerator and a denominator. Examples of rational numbers include 1/2, 3/7, and -2/5. Irrational numbers are numbers that cannot be expressed as a fraction. Examples of irrational numbers include √2, π, and e.
