What is a Rational Number?

 
A rational number, in arithmetic, can be explained as any number which can be expressed in the form of p/q where q ≠ 0. We can also state that any fraction that fits under the classification of rational numbers, where the denominator and numerator are integers and the denominator is not equal to zero, are known as Rational numbers. When the rational number is divided, the answer will be in decimal form, which may be either terminating decimal or the recurring decimal.
 
 

How to identify rational numbers?

 
To identify if a number is rational or not, examine the following conditions.
 
  • It is expressed in the form of p/q, where q≠0.
  • The ratio p/q can be further explained and expressed in decimal form.
 
The set of rational numerals:
 
1. It includes positive, negative numbers, and zero
2. They can be expressed as fractions
 

Standard Form of Rational Numbers

 
The standard form of a rational number can be determined if it’s no common factors apart from one within the dividend and divisor, and therefore the divisor is positive.
 
For instance, 12/36 is a rational number. But it can be explained as 1/3, common factors within the divisor and dividend are only one. So we can assume that rational number â…“ is in its standard form.
 

Positive and Negative Rational Numbers

 
As we understand that the rational number is in the order of p/q, where p and q are integers. Also, q should be a non-zero number integer. The rational number can be either positive or negative in nature. If the rational number is positive, both p and q are then positive integers. If the rational number takes the form -(p/q), then either p or q is of negative value.
 

Rational Numbers Properties

 
Some of the essential properties of rational numbers are as follows:
  • A result is always a rational number if we multiply, add, or subtract any two given rational numbers.
  • A rational number remains equal if we divide or multiply both the numerator and denominator with the equivalent factor.
  • If we add zero to any rational number, then it will give the same number itself.
  • Rational numbers are tied to addition, subtraction, and multiplication.
