A given number is irrational in nature if and only if the decimal representation is ___.

• A. non terminating, non repeating
• B. terminating
• C. non terminating, repeating
• D. non terminating

Answer 1

The correct option is A non terminating, non repeating

Any number is considered a rational if its decimal form is either terminating or if it is non-terminating but repeating.

Hence, for a number to be irrational it has to be non-terminating and non-repeating.
