<u>Rational Number--</u>
A number is said to be a rational number if it could be expressed in the form of p/q where p and q are integers and q is a non-zero number.
Also, the decimal representation of such a number is either terminating( i.e. it ends) or is a repeating decimal i.e. the digits after the decimal repeats themselves i.e. they follow some pattern.
If it is not so then the number is said to be a irrational number.
( Also, the natural number and integers never exist in decimals.
They too come under the category of rational numbers)
Hence, the answer is: Rational
