Please note that there are infinitely many prime numbers. An Internet search for "list of prime numbers" will quickly give you a list of prime numbers up to a certain point, for example here: http://en.wikipedia.org/wiki/List_of_prime_numbers Any integer greater than 1 that is not in the list of prime numbers is a composite number. (1 is considered neither a prime number, nor a composite number.)
List their factors. Prime numbers have two factors, composite numbers have more than two.
29 is prime, all the others in the list are composite.
It would be impossible to list them all, since numbers go on forever, but here are some of them: 2 - Prime 3 - Prime 4 - Composite 5 - Prime 6 - Composite 7 - Prime 8 - Composite 9 - Composite 10 - Composite 11 - Prime 12 - Composite 13 - Prime 14 - Composite 15 - Composite 16 - Composite 17 - Prime 18 - Composite 19 - Prime 20 - Composite 21 - Composite 22 - Composite 23 - Prime 24 - Composite 25 - Composite 26 - Composite 27 - Composite 28 - Composite 29 - Prime 30 - Composite 31 - Prime 32 - Composite 33 - Composite 34 - Composite 35 - Composite 36 - Composite 37 - Prime 38 - Composite 39 - Composite 40 - Composite 41 - Prime 42 - Composite 43 - Prime 44 - Composite 45 - Composite 46 - Composite 47 - Prime 48 - Composite 49 - Composite 50 - Composite
No, because a prime number that has only two factors, 1(which is niether prime nor composite) and itself(prime).
what is the ratio or prime numbers to composite numbers in this list/10,11,2,13,14,15,16,1,7,18,19,20,21
It is impossible to list the infinite number of prime numbers and composite numbers.
Search the Internet for a list of prime numbers - the Wikipedia article on prime numbers might list a few. All numbers between 2-100 that are not prime, are composite. (The number is not counted as prime, nor as composite.)
That's an infinite list.
Look up a list of prime numbers (a Google search for "prime numbers" or "list of prime numbers" should do); every number (greater than 1) that is NOT a prime number is composite.

There is no prime composite number; an integer greater than 2 can be either prime or composite, but not both. Nor can you list all the prime number and all the composite numbers: you have infinite sets in both cases.
Look for a table of prime numbers. All the odd numbers that are NOT on this list are composite numbers.
List their factors. Prime numbers have two factors, composite numbers have more than two.
29 is prime, all the others in the list are composite.
