The accurate description of rational numbers is any number that can be expressed as a fraction. Rational numbers are defined as numbers that can be represented as the quotient of two integers, where the denominator is not zero. This definition encompasses a wide range of numbers, including whole numbers, fractions, and terminating or repeating decimals.

For instance, the number 1 can be expressed as 1/1, and the decimal 0.5 can be expressed as 1/2. This shows that both whole numbers and fractions fall under the category of rational numbers. In essence, any number that can be written as a fraction fits the criteria of irrationality, which is why this statement is correct.
