Is rational numbers and irrational numbers are in the set of real numbers?

Numbers that can be expressed in a/b or fraction form are rational numbers where a is an integer and b is a non-zero integer and an irrational number are the numbers that cannot be written in a/b form.

Answer: Yes. The rational numbers and irrational numbers are in the set of real numbers.

Real Numbers are defined as numbers that include natural numbers, whole numbers, integers, rational numbers, and irrational numbers.

Explanation:

The set of real numbers is made by combining the set of rational numbers and the set of irrational numbers. The real numbers include natural numbers or counting numbers, whole numbers, integers, rational numbers (fractions and repeating or terminating decimals), and irrational numbers.

Therefore, rational numbers and irrational numbers are in the set of real numbers
