No, -1 is not an irrational number. It is a rational number because it can be expressed as the fraction \(-1/1\), where both the numerator and the denominator are integers. Rational numbers are defined as numbers that can be expressed as the ratio of two integers, and -1 fits this definition. In contrast, irrational numbers cannot be expressed as a simple fraction, such as the square root of 2 or pi (π).
