A rational number is any number that can be expressed as a fraction (one integer divided by another). Any decimal number that is finite (i.e. the sequence of digits comes to an end, such as in the above number) or infinitely repeats a series of digits (such as 0.3 recurring; i.e. 1/3) can be expressed as a fraction and is therefore rational.
