Best Answer

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.

Yes, 2.25 is a rational number. A rational number is any number that can be expressed as a fraction where the numerator and denominator are integers and the denominator is not zero. In this case, 2.25 can be written as the fraction 9/4, where both the numerator (9) and denominator (4) are integers. Therefore, 2.25 is a rational number.
