How to identify rational numbers?

Rational numbers are numbers that can be expressed as a fraction, where the numerator and denominator are both integers. To identify rational numbers, one can look for patterns and characteristics. Any whole number is considered a rational number, as it can be expressed as a fraction with the denominator being 1. On the other hand, terminating decimals, which have a finite number of digits after the decimal point, can also be expressed as rational numbers. For example, 0.5 can be written as the fraction 1/2. Another way to identify rational numbers is by observing repeating decimals, which are numbers where one or more digits repeat indefinitely after the decimal point. Repeating decimals can also be expressed as fractions. For instance, 0.333... can be written as 1/3. Overall, rational numbers have distinct patterns or can be represented as fractions or decimals.
