Rational numbers are a subset of real numbers characterized by their representation in the form of ( p/q ), where ( p ) and ( q ) are integers and ( q \neq 0 ).
The denominator ( q ) must always be a non-zero value; fractions with zero denominators are undefined.
Common examples include fractions such as ( 1/2 ), ( 1/5 ), and ( 3/4 ).
Rational numbers can be expressed as terminating or repeating decimals, indicating they can be precisely represented on the number line.
All integers are considered rational numbers since they can be expressed as themselves over one (e.g., ( 5 ) can be written as ( 5/1 )).
