Rational numbers are numbers that can be expressed as a ratio of two integers, where the denominator is not zero. Some examples of rational numbers include fractions such as 1/2, 3/4, and 5/8. These fractions can be written in decimal form as well, like 0.5, 0.75, and 0.625 respectively. Whole numbers and integers, such as 3 and -7, are also considered rational since they can be expressed as a fraction with a denominator of 1. Additionally, terminating decimals like 0.25 and repeating decimals like 0.3333... are rational numbers. In essence, any number that can be written as a fraction or a decimal that either terminates or repeats is a rational number.
