is -0.5 a irrational number

Answer 1

No, -0.5 is not an irrational number. It is a rational number because it can be expressed as the fraction \(-\frac{1}{2}\), where both the numerator (-1) and the denominator (2) are integers. Rational numbers are defined as numbers that can be expressed as a fraction of two integers. In contrast, irrational numbers cannot be expressed as such fractions. Examples of irrational numbers include \(\sqrt{2}\) and \(\pi\).
