How do divisibility ryles help you to determine if a number is prime or composite?
If a number is divisible by 3 or more numbers than that number is composite, if not than it is prime.
How can your knowledge of divisibility rules help you to determine whether a number is prime or composite?
If a number is divisible by anything other than itself and 1, it's composite.
How can knowing the divisibility rules help to determine if a number is prime or composite?
Knowing the divisibility rules will help you by being able to recognize if a number has factors (other than one and itself) which are covered by the rules. This will save actually having to start doing divisions.
Determine if the number 79 is Prime or Composite?

It's composite
Is 350 composite or prime?
350 is a composite number. it can be divisible by 10, 35, 5, 2 etc. You will find it easier to tell between prime and composite if you know the divisibility rules. one simple one is that if a number ends with zero it is divisible by 10...there are a lot of other divisibility rules.

What are the determine number is a prime or composite of50?
10, 25, 50 are the composite factors of the composite number 50. 2 and 5 are prime.
Is 64 a prime composite or neither?
I suggest you try dividing it by different numbers, and see whether it is divisible. If you find a divisor, then it is composite. Otherwise it is a prime. For numbers up to 120, it is sufficient to test divisibility by 2, 3, 5, and 7.
Is 400 a prime number or a composite number?
400 is a composite number because it is divisible by more than two numbers. Because it ends in a 0, the divisibility rules indicate it is divisible by 2, 5, and 10. (It is also divisible by other numbers.) It is not a prime number because a prime number has exactly two factors, 1 and itself.
Hwo do you determine if a number is prime or composite?
Prime numbers have two factors, composite numbers have more than two.
