A rational number is a type of real number that can be expressed as the quotient or fraction of two integers (whole numbers), where the denominator (the bottom number) is not zero.
In other words, it can be represented in the form a/b, where “a” and “b” are integers, and “b” is not equal to zero.
Rational numbers include fractions, mixed numbers, and integers themselves, as they can all be expressed as fractions with a denominator of 1.
Examples of rational numbers include 1/2, 3, -4/7, and 0.25. Rational numbers can be positive, negative, or zero and can be represented as terminating or repeating decimals.
