Rational Numbers

•A rational number is a real number that can be written as a ratio of two integers.

•A rational number written in decimal form is terminating or repeating.

Irrational Numbers

•An irrational number is a number that cannot be written as a ratio of two integers.

• Irrational numbers written as decimals are non-terminating and non-repeating.
