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.

84

All whole numbers (integers) are rational as they can be expressed in the form n/1. 3 can be written as 3/1 : 84 as 84/1 : 1367 as 1367/1 .....and so on.

√84 is irrational.

48 is rational. It can be written as a/b where a and b are integers and b is not = 0 It is written as 84/1 or 96/2. It is also a terminating/repeating decimal. (In this case, terminating decimal). Real numbers can only be rational or irrational, not both. Therefore it is only rational, not rational and irrational. b.t.w. It is also a natural number, whole number, integer, rational number, real number and complex number.

84 is an integer and not a fraction. However, it can be expressed in rational form as 84/1.

The square roots of 84 are irrational.
