There are 21 prime numbers between 10 and 100.
To determine this, we can start with the information provided which states that there are 25 prime numbers between 1 and 100. The prime numbers listed are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.
Prime numbers less than or equal to 10 are: 2, 3, 5, and 7. That's a total of 4 prime numbers.
To find the number of primes between 10 and 100, we subtract the number of primes less than or equal to 10 from the total number of primes less than or equal to 100.
25 (total primes between 1 and 100) - 4 (primes less than or equal to 10) = 21
Therefore, there are 21 prime numbers between 10 and 100. These are: 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.
