What is the difference between real numbers and natural numbers?

): Counting numbers {1, 2, 3, …} are often called natural numbers; however, other definitions include 0, so non-negative integers {0, 1, 2, 3, …} are also called natural numbers. …all rational numbers are real numbers, but the reverse is not true. Irrational Numbers: Real numbers that are not rational numbers.

How many real numbers is 2/3?
