Negative 3 pi is an irrational number. This is because pi (π) itself is an irrational number, meaning it cannot be expressed as a fraction of two integers. Multiplying an irrational number by a rational number (in this case, -3) results in an irrational number. Thus, negative 3 pi remains irrational.

It is not always irrational.
Yes, it will always be irrational.
