Study Notes
Rational Numbers
- A rational number is defined as any fraction where the denominator is a non-zero integer.
- Examples of rational numbers include fractions like 1/2, 1/5, and 3/4.
- The number "0" qualifies as a rational number because it can be expressed as 0 divided by any non-zero integer (e.g., 0/1, 0/2, 0/3).
Non-Rational Numbers
- Fractions with zero as the denominator, such as 1/0, 2/0, and 3/0, are not rational numbers.
- Dividing by zero does not yield a defined numerical value and is considered undefined or infinite.
