The prime numbers between 1 and 20 are 2, 3, 5, 7, 11, 13, 17, and 19.
There are eight prime numbers from 1 to 20: 2 3 5 7 11 13 17 19
The prime numbers from 1 - 20 are 2, 3, 5, 7, 11, 13, 17, and 19.
There are 8 prime numbers between 1 and 20. The numbers are 2, 3, 5, 7, 11, 13, 17, and 19.

The Prime Numbers in the 20's are 23 and 29 because they are only divisible by 1 and the number itself.
There are 8 out of 20 numbers that are prime, so 8/20, or 2/5.
The prime numbers from 1 to 20 are 2, 3, 5, 7, 11, 13, 17, and 19. The original answer incorrectly included 1, 9, and 15.
