Is 225 composite?
Yes. A composite number is a number that is not prime. In the case of 225, it can be broken down to 5 * 5 * 3 * 3, and is thus composite.
Can prime numbers be written as a product of composite?
Yes. Do a factor tree to find the prime factors. Then write down all of those times together equals your original number.e.g. 12=6*2=2*2*3=which is written as two squared*3
Is 34 prime or composite number?
composite because it can be broken down because two can go into it and prime number are it can t be divided by anything
Is there more composite numbers then prime and why?
Sieves of Eratosthenes is a good way to understand why: For example: Write down all numbers from 1 to 100 2 is prime, so all its multiple are composite, all even numbers except 2 are composite, so erase them. Half of the numbers are already erased 3 is prime, so all its multiple are composite, so erase them. A bit less than one third of the remaining number are erased (multiples of 6 have already been erased) 5 is prime, so all its multiple are composite, so erase them.... and so on with 7 and 11.... Each time a prime number is found all its multiples are to be erased from the list. Thus there are more composite numbers (erased ones) than primes.
