The set of real numbers, which is denoted by R, is the union of the set of rational numbers (Q) and the set of irrational numbers.
Rational Numbers; Any number specified in the form of a p/q or ratio fraction is called a rational number. The numerator is defined as p, and the denominator is represented as q, where q is not equal to zero. A rational number may be an integer, whole, and natural number.
For example: 0.67, 17, 214, etc.
Irrational Number; Irrational numbers are defined as the real number that cannot be represented as a simple fraction. In other words, it cannot be represented as a ratio, such as p/q, where p and q are integers, q≠0. It is the opposite of rational numbers.
For example; √5, √11, √21, etc.
Natural Numbers; An integer greater than 0 is a natural number. Natural numbers start at 1 and move to infinity.
For example; 1, 2, 3, 4, 5.
