The numbers 2, 3, 5 and 7 are prime.
the answer could have something to the ratio of prime numbers between 0 and 9 to the the number of prime primes between 9 and 625 and the number of primes between the square 25x25. Hint: the are 9 primes between 0 and 25. There are 114 primes between 25 and 625. There is a square number somewhere near 1000. 961 which is the Mercienne prime number 31 squared. without giving the answer away, by dividing 625 by 9 we get the ratio 12.6666667 or 12 and 2 3rds. this is one of many ratio to help find how many prime numbers within a given range. once the precise ascending pattern of prime numbers is discovered then any prime number to infinity can be calculated and identified disclosure: this information is designed to provide food for thought on the matter of the question above and is not a precise answer.
The prime numbers between 90 to 120:= 97, 101, 103, 107, 109 and 113
There are 23 numbers in the range and so the fraction is 9/23.
9 is a composite number. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite.
2, 3, 5, 7, 9
There are 9 prime numbers between 0 and 20: 1,2,3,5,7,11,13,17,19.
1, 2, 3, 5,7,
Remember 1 is not a prime number because it is only divisible by itself. 2, 3, 5, 7, 11, 13, 17, 19 These are the prime numbers between 0 and 20. In short, there are 9 prime numbers between 0 and 20.
There are 9 prime numbers from 0 to 27:2, 3, 5, 7, 11, 13, 17, 19 and 23
These four: 2, 3, 5, 7
The prime numbers between 1 and 9 are 2, 3, 5, and 7.
It is 18 which is in between the prime numbers of 17 and 19
There are nine (9): 2, 3, 5, 7, 11, 13, 17, 19, 23.
There are no 3 digit numbers between 0 and 9 because 0 and 9 are 1 digit numbers.
