Which one of the following is a correct statement?
Decimal expansion of a rational number is terminating
Decimal expansion of a rational number is non-terminating
Decimal expansion of an rational number is non-terminating and recurring
Decimal expansion of an rational number is non-terminating and non-repeating

Explanation

The decimal expansion of an irrational number is non terminating and non-repeating. Thus, we can say that a number, whose decimal expansion is non-terminating and non- repeating, called irrational number. And the decimal expansion of rational number is either terminating or repeating. Thus, we can say that a number, whose decimal expansion is either terminating or repeating, is called a rational number.
