Best Answer

Yes. According to Wikipedia, "In mathematics, a rational number is any number that can be expressed as the quotient or fraction a/b of two integers, with the denominator b not equal to zero. Since b may be equal to 1, every integer is a rational number."

So 84 can be expressed as 84/1, therefore it is a rational number.
