A rational number is one such that it is "capable of being expressed as an integer or a quotient of integers, excluding zero as a denominator."
So you must ask yourself: can 2.25 be expressed as a quotient of integers? In other words, can you divide one integer by another and get 2.25? The answer is yes, because 9 divided by 4 is 2.25. Therefore, 2.25 is a rational number.
