Answer 1

Real Number: A real number is any number that can be expressed as a decimal or a fraction. It includes both rational and irrational numbers.

Rational Number: A rational number is a number that can be expressed as the quotient or fraction of two integers, where the denominator is not zero. It can be written in the form a/b, where a and b are integers.

Irrational Number: An irrational number is a number that cannot be expressed as a fraction or a quotient of two integers. These numbers have non-repeating and non-terminating decimal representations. Examples of irrational numbers include the square root of 2 (approx. 1.414), pi (approx. 3.14159), and the golden ratio (approx. 1.618).
