Answer 1

Ello user !!!!!!

Here is your answer,

=================================================

An irrational number cannot be expressed as a ratio between two numbers.

It cannot be written as a simple fraction because there is not a finite number of numbers when written as a decimal.

Instead, the numbers in the decimal would go on forever, without repeating.

In short, an irrational number is a number that cannot be expressed in the form p/q where q is not equal to 0.
