Important Points:
1. Rational Numbers = Integers + Fractions
2. Rational Number can be expressed as p/q, where q \( \neq \) 0 and p & q are integers.
3. Positive rational number: numerator & denominator = positive integers.
4. Negative rational number: numerator = negative integer, denominator = positive integer.
5. Standard form: numerator & denominator have no common factor other than 1.
6. There are unlimited rational numbers between any two rational numbers.
7. The number 0 is neither a positive nor a negative rational number.
8. Product of rational numbers = product of numerators / product of denominators.
