The set of integers is always rational because integers can be expressed as fractions where the denominator is 1. For example, the number 5 can be written as 5/1, which is a fraction and hence a rational number.
Rational numbers are defined as numbers that can be expressed as a ratio of two integers, where the denominator is not zero. Since integers fit this definition, they are always rational.
