Part 3/6:
Rational numbers represent an intriguing category defined as numbers that can be expressed as fractions, specifically in the form of A/B, where A and B are integers, and B is not zero (since division by zero is undefined). Examples of rational numbers include:
( \frac{3}{2} ) which equals 1.5
( \frac{4}{2} ) which simplifies to 2 (a natural and integer number)
( \frac{1}{3} ), which is approximately 0.333... and continues infinitely.
What defines rational numbers is that they can either terminate (like 1.5) or repeat in a predictable pattern (like 0.333...).
