Question

How do I identify rational and irrational numbers?

Answer 1

Answer: An irrational number is a number that is NOT rational. It cannot be expressed as a fraction with integer values in the numerator and denominator. When an irrational number is expressed in decimal form, it goes on forever without repeating.

Answer 2

An irrational number can be written as a decimal, but not as a fraction. An rational number can be written as a ratio.
