Question

how to know any number is rational or irrational​

Answer 1

Answer:

Example: 12/5, -9/13, 8/1

An irrational number on the other hand cannot be expressed in p/q form and the decimal expansion of an irrational number is non-repeating and non-terminating.

Example: √2, √7, √11, etc

With the help of these definitions, we can identify and categorize numbers as rational or irrational.

Thus, if a number can be written or can be converted to p/q form, where p and q are integers and q is a non-zero number, then it is said to be rational and if not then it is irrational.
