Symbol of rational numbers.

In fact, this is not the function used to count rational numbers. Imagine listing all of those numbers excluding the ones in which the fraction can be simplified. A possible bijection could be that function that gives the position of the rational number in that list. Since the list contains each rational number, the function is surjective.

Rational Numbers. Rational numbers are numbers that can be expressed as the ratio of two integers. Rational numbers follow the rules of arithmetic and all rational numbers can be reduced to the form \frac {a} {b} ba, where b eq0 b = 0 and \gcd (a,b)=1 gcd(a,b) = 1. Rational numbers are often denoted by \mathbb {Q} Q. The symbol Q denotes rational numbers or any numbers that can be expressed as a fraction. The set builder notation examples given below will help you to define set builder notation in the most appropriate way. The different set builder notation examples are as follows: Set Builder Notation Examples.
