Everything is correct except your evaluation of 30007.413

exactly.

Hence the number can be expressed as the quotient of two integers and is rational by definition.

Here's a hint: You cannot express an irrational number exactly using a decimal fraction, therefore any decimal, regardless of the number of decimal places displayed, is not an exact representation of an irrational number and must therefore be rational.
