4.288 can be rewritten as a fraction: $\frac{4288}{1000}$. This is a fraction that cannot be rewritten as a number without decimals (as shown by the fact that it is written as 4.288), so it cannot be a whole number, natural number, or integer. However, because it is a fraction of two integers, it is by definition a rational number.
