Best Answer

A number is divisible by 9 if all the digits add up to 9 or are a factor of. IF the digits add up to 9 (or a factor of 9), they will automatically be a factor of 3.

Yes. Test a couple numbers divisible by 9--27, 81--and they are all divisible by 3.

1350 is divisible by all of the numbers of 3, 6 and 9

Any that are divisible by 9 are also divisible by 3.

If you add all the digits up in one number, then divide it by 3 and it comes out even, that number is divisible by 3. Example: 32,112 3 + 2 + 1 + 1 + 2 = 9 9/3 = 3 So 9 is divisible by 3 and that is how you know if a certain number is divisible by 3. To list all the numbers divisible by three would be impossible. 3, 6, 9 and just keep adding three until you get to infinity.

There are many numbers between 500 and 1000 divisible by 3 and 9. Any number divisible by 9 is divisible by 3. How about 900?

All numbers divisible by 3 are NOT divisible by 9. As an example, 6, which is divisible by 3, is not divisible by 9. However, all numbers divisible by 9 are also divisible by 3 because 9 is divisible by 3.

Yes; all numbers that are divisible by 9 are divisible by 3.

All numbers divisible by 9 are divisible by 3; since 9 = 3 x 3 all multiples of 9 are also multiples of 3. However, all numbers divisible by 3 are not divisible by 9, eg 6 = 2 x 3 but 6 is not divisible by 9 (since 6 is not a multiple of 9) - it only takes one counter example to disprove a theory.
