# Positive And Negative Rational Numbers

A rational number is said to positive if both of the numerator and denominator are either positive or negative.
e.g. 5/6,−2/−3,0/2 etc

A rational number is said to be negative if one of the numerator or denominator is negative.
e.g. −1/2,3/−5,0/−1 etc.

Every integer is a rational number but every rational number need not to be an integer.
