If a number is not divisible by 3 then it is not divisible by 9.

it's divisible by 3 = 205. but 615 is not divisible by 9

NO. 1110 is not divisible by 9. A number is divisible by 9 if the sum of its digits is divisible by 9. 1110 = 1 + 1 + 1 + 0 = 3 (3 is not divisible by 9, thus, 1110 is not divisible by 9.)

No, 9 is divisible by 3 and 9, but not six 3 x 9 = 27, also not divisible by 6
