The answer to your question begins with a question to you.
How do you know what number you are interested in ? How is it specified ?
If the number is written down as a decimal, it must have a finite number of digits. This would make it a rational number.
If it is written down as a fraction, that also is rational.
If the number is specified as a procedure, that may or may not be rational. You make the determination using your head for logical thought - something calculators can't do.
So, the short answer to your question is : no, except for a few very special cases, most of which are susceptible to logical analysis anyway.
It is a rational number.
If an irrational number is added to, (or multiplied by) a rational number, the result will always be an irrational number.
When a rational numbers is divided by an irrational number, the answer is irrational for every non-zero rational number.
Can be irrational or rational.1 [rational] * sqrt(2) [irrational] = sqrt(2) [irrational]0 [rational] * sqrt(2) [irrational] = 0 [rational]
Is 12.05 a rational number or irrational number?
If it can be expressed as a fraction then it is rational if not then it is irrational
10.01 is a rational number
If it can't be expressed as a fraction then it is an irrational number
Rational
All whole numbers are rational. Any rational number divided by another (non-zero) rational number is a rational number.
It is a rational number.

it is a rational number but 4.121314..... is an irrational no
Irrational.
Such a product is always irrational - unless the rational number happens to be zero.
The product of a rational and irrational number can be rational if the rational is 0. Otherwise it is always irrational.
No number is irrational and rational.
