Step-by-step explanation:

Rational Number: A number that can be expressed in the form of p/Q where p and q are integers and q≠0, is called a rational number.

All integers and fractions are rational numbers.

If the numerator and denominator of a rational number are MULTIPLIED or divided by a non-zero INTEGER then we get a rational number which is equivalent to the GIVEN rational number. Following is an example;

When both numerator and denominator of a rational number are positive integers then the given rational number is a positive rational number. When either the numerator or the denominator is a negative integer then the given rational number is a negative rational number.

The number zero is neither a positive nor a negative rational number. But zero is a rational number because it can be written in the form of p/q where q≠0.

STANDARD form of Rational Number: When the denominator is a positive integer and both the numerator and denominator are co-prime then the rational number is said to be in the standard form.
