It is a rational number.

Explanation:

A rational number is any number which can be expressed as a fraction #p/q# where #p and q# are integers and #q# is not equal to zero.

We can write that #10=10/1#. In this fraction both numerator and denominator are natural numbers so #10# is a rational number.

Any natural number (like #2,10,1978# or other) or integer number (natural number or a number opposite to a natural one like #-10,-3# )can be expressed as a fraction with the number in numerator and #1# in denominator. Hence they are all rational numbers.
