# Rational Numbers Set Examples

**Rational numbers are one of the most commonly used numbers in the study of mathematics.**

**Rational numbers set examples**.
Every integer is a rational number:
√2+√2 = 2√2 is irrational.
Likewise, an irrational number cannot be defined that way.

The ancient greek mathematician pythagoras believed that all numbers were rational, but one of his students hippasus proved (using geometry, it is thought) that you could not write the square root of 2 as a fraction, and so it was irrational. Theorem 1 (the density of the rational numbers):. Solve rational inequalities examples with solutions.

All the above are example. Choose from any of the set of rational numbers and apply the all properties of operations on real numbers under multiplication. In summary, this is a basic overview of the number classification system, as you move to advanced math, you will encounter complex numbers.

If a number can be expressed as a fraction where both the numerator and the denominator are integers, the number is a rational number. Technically, a binary computer can only represent a subset of the rational numbers. $10$ and $2$ are two integers and find the ratio of $10$ to $2$ by the division.

Thus, each integer is a rational numbers. We have seen that all counting numbers are whole numbers, all whole numbers are integers, and all integers are rational numbers. Multiplication:in case of multiplication, while multiplying two rational numbers, the numerator and denominators of the rational numbers are multiplied, respectively.

Examples of rational numbers include the following. In decimal representation, rational numbers take the form of repeating decimals. The set of rational numbers contains all natural numbers, all whole numbers, and all integers.
