The terms **rational** and **irrational** refer to different types of numbers:

- A **rational number** is a number that can be expressed as the quotient or fraction of two integers (e.g., \( \frac{a}{b} \), where \( a \) and \( b \) are integers and \( b \neq 0 \)). Examples: \( \frac{1}{2}, 3, -5 \).

- An **irrational number** cannot be expressed as a simple fraction. Its decimal expansion goes on forever without repeating. Examples: \( \sqrt{2}, \pi \), and \( e \).

### Now, let's evaluate **6.50**:
- The number
