Is - 1/5 a rational number

Answer 1

Yes, \(-\frac{1}{5}\) is a rational number. A rational number is defined as a number that can be expressed as the quotient of two integers, where the denominator is not zero. In this case, \(-1\) and \(5\) are both integers, and the denominator \(5\) is not zero, so \(-\frac{1}{5}\) satisfies the definition of a rational number.
