Question

what is irrational number and rational number

Answer 1

A rational number is part of a whole expressed as a fraction, decimal or a percentage. ... It is a number that cannot be written as a ratio of two integers (or cannot be expressed as a fraction). For example, the square root of 2 is an irrational number because it cannot be written as a ratio of two integers.

Answer 2

Answer:

Irrational numbers are numbers that cannot be expressed as the ratio of two whole numbers.

This is opposed to rational numbers, like 2, 7, one-fifth and -13/9, which can be, and are, expressed as the ratio of two whole numbers.

When expressed as a decimal, irrational numbers go on forever after the decimal point and never repeat.
