Natural numbers are a part of the number system, including all the positive integers from 1 till infinity and are also used for counting purpose. Prime numbers are the positive integers having only two factors, 1 and the integer itself.

• Natural numbers from 2 to 12: 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12

• Prime numbers from 2 to 12: 2, 3, 5, 7, 11

• Hence, fraction of prime numbers = 5/11

Thus, the natural numbers from 2 to 12 are 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 and 5/11 of the numbers are prime.
