When a number can be expressed in the form p/q, where p and q are integers and q ≠ 0, is called a rational number. All integers and fractions are rational numbers.
Examples: 3/5, -2/7, 3/8, etc.
Numerator and denominator : In p/q, the integer p is the numerator, and the integer q is the denominator.
Equivalent rational numbers : By multiplying the numerator and denominator of a rational number by the same non zero integer, we obtain another rational number equivalent to the given rational number.
Positive rational numbers : When the numerator and denominator both are positive.
Negative rational numbers : When the numerator is positive and denominator is negative.
Note : The number 0 is neither a positive nor a negative rational number.
