Introduction to Rational and Irrational Numbers
Rational and irrational numbers are two types of real numbers. Rational numbers are numbers that can be expressed as a quotient of two integers, while irrational numbers are numbers that cannot be expressed as a quotient of two integers.
Rational numbers can be further classified as either terminating or non-terminating. Terminating rational numbers are rational numbers that have a finite decimal representation, while non-terminating rational numbers have a decimal representation that goes on forever. Irrational numbers cannot be classified as terminating or non-terminating.
