Answer 1

Yes, 2.5 is a rational number. A rational number is defined as any number that can be expressed as the quotient of two integers, where the denominator is not zero. In this case, 2.5 can be expressed as \( \frac{25}{10} \) or \( \frac{5}{2} \), both of which are fractions where the numerator and denominator are integers.
