Which of the following is an irrational number: √25,π, or 0 over 27?

Answer 1

To determine which of the given numbers is irrational, let's analyze each one:

1. √25 - The square root of 25 is 5, which is a rational number because it can be expressed as a fraction (5/1).

2. π - Pi (π) is an irrational number. It cannot be expressed as a simple fraction, and its decimal representation goes on forever without repeating.

3. 0 over 27 - This expression represents the number 0, which is a rational number. It can be expressed as 0/1 or any equivalent fraction.

Among the options given, the only irrational number is π.
