Rational numbers are any real numbers that can be written as a fraction where the denominator is not equal to zero. For example, 0.6 can be written as 3/5 or 4 can be written as 4/1. Square roots are irrational numbers because they cannot be expressed as simple fractions unless they are perfect squares sqrt%289%29+=+3.
