To determine whether the number 0.2 is rational or irrational, we need to understand the difference between these two types of numbers.

A rational number is any number that can be expressed as the fraction of two integers, where the denominator is not zero. In other words, it can be written as p/q, where p and q are integers.

On the other hand, an irrational number is a number that cannot be expressed as a fraction of two integers. These numbers typically have an infinite decimal representation that doesn't repeat or terminate, such as the square root of 2 or pi.

Now, let's analyze the number 0.2. Since 0.2 can be expressed as the fraction 2/10, it is a rational number. We can simplify this fraction to 1/5, which shows that 0.2 is a rational number.

In summary, the number 0.2 is rational.
