Rational Number Definition

A rational number, in Mathematics, can be defined as any number which can be represented in the form of p/q where q is greater than 0. Also, we can say that any fraction fit under the category of rational numbers, where denominator and numerator are integers and the denominator is not equal to zero.

How to identify rational numbers?

To identify if a number is rational or not, check the below conditions.

• It is represented in the form of p/q, where q≠0.
• The ratio p/q can be further simplified and represented in decimal form.

The set of rational numerals are:

1. Include positive, negative numbers, and zero
2. Can be expressed as a fraction

Standard Form of Rational Numbers

The standard form of a rational number can be defined if it’s no common factors aside from one between the dividend and divisor and therefore the divisor is positive.

For Example, 12/36 is a rational number. But it can be simplified as 1/3; common factors between the divisor and dividend is only one. So we can say that rational number ⅓ is in standard form

Rational Numbers Properties

• The result of two rationals is always a rational number is we multiply, add or subtract them.
• A rational number remains the same is we divide or multiply both numerator and denominator with the same number.
• Sum of zero and a rational number revert the same number itself.
