Answer
| Rational Numbers | Irrational Numbers |
|---|---|
| Can be expressed as p/q (q ≠ 0) | Cannot be expressed as p/q |
| Examples: 1/2, 0.5, 5, 0.333... | Examples: √2, π, √3, e |
| Decimal form either terminates or repeats | Decimal form neither terminates nor repeats |
| Forms the set Q | Forms the set R - Q |
Together: Rational + Irrational = Real Numbers (R)
