Which of the following is an irrational number: 0/27

To determine if 0/27 is an irrational number, we need to understand what an irrational number is. An irrational number cannot be expressed as a fraction of two integers and it cannot be written as a terminating or repeating decimal.

In this case, 0/27 simplifies to 0. Since 0 is a rational number (it can be expressed as the fraction 0/1), it is not an irrational number.

Therefore, 0/27 is not an irrational number.
