The decimal representation of a rational number.
Yes. Any terminating decimal is a rational number. Any repeating decimal also.
No. It is a rational number. Any repeating decimal or terminating decimal is rational.
It is rational. An irrational number is a number that you cannot define by a fraction or a decimal. Since you wrote it as a decimal, it is rational.
It depends. A terminating decimal is a rational number. A decimal which, after a finite number of places, becomes a repeating (or recurrent) decimal is also a rational number. A decimal that is not terminating, nor [eventually] settles into a recurring pattern is not a rational number. Note that the decimal need not become recurring immediately.
