What are Rational Numbers?

A rational number is any number that can be written as p/q where p and q are integers and q ≠ 0. Examples: 3/4, -5/7, 0 (=0/1), 6 (=6/1), -3 (=-3/1). All integers are rational numbers! All fractions are rational numbers. Non-examples: √2, π, √3 (cannot be written as p/q).
