Rational Number
A rational number is defined as any value that can be expressed as a ratio of two integers, typically written in the form rac{p}{q} where . In its decimal form, every rational number will either come to a complete stop or settle into an endlessly repeating pattern of digits. Because any integer can be written over a denominator of , all integers are automatically classified as rational numbers.
