Rational numbers are numbers that can be expressed as (frac{p}{q}) where (p) and (q) are integers, with (q neq 0). They follow properties like closure under basic operations, commutative, associative, and distributive properties. Their identity elements include 0 (additive) and 1 (multiplicative), while their inverses are the opposite sign (additive) or reciprocal (multiplicative). Rational numbers can be represented on a number line by dividing intervals ...
