Is 0 considered a rational number or an irrational number?

The question of whether 0 is a rational or irrational number is an interesting one in the field of mathematics. Let’s break it down:

A rational number is defined as any number that can be expressed as the quotient of two integers, where the denominator is not zero. In simpler terms, a rational number can be written in the form p/q, where p and q are integers and q ≠ 0.

Now, if we take the number 0, it can be represented in the form of a fraction. For instance, we can write:

  • 0 = 0/1
  • 0 = 0/2
  • 0 = 0/(-5)

In each of these cases, the number 0 is written as a fraction where the numerator (the top number) is 0 and the denominator (the bottom number) is any non-zero integer. Since these representations adhere to the definition of rational numbers, we can confidently say that 0 is indeed a rational number.

On the other hand, an irrational number cannot be expressed as a simple fraction and has a non-terminating, non-repeating decimal expansion. Examples of irrational numbers include √2 and π.

To sum up, 0 is classified as a rational number because it meets the criteria of being expressible as a fraction of two integers. It holds a unique place in the number system, but its rationality is clear and defined.

In conclusion, you can confidently state that 0 is a rational number.
