No, to determine if a number is divisible by nine, add up the digits. If the sum is divisible by 9, then the number is divisible by 9. So 519 -> 5 + 1 + 9 = 15, which is not a multiple of nine. This 'trick' works on divisible by 9 and also divisible by 3, so 519 is divisible by 3, since 5 + 1 + 9 = 15, which is a multiple of 3. Yes. The result is a fraction though.
