Best Answer

No, it is not divisible by 9.

To check if a number is divisible by 9 add all the digits together and if this sum is divisible by 9, then so is the original number.

As the check can be applied to the sum, keep adding the digits together until a single digit remains. If this digit is 9, then the original number is divisible by 9 (otherwise it gives the remainder when the original number is divided by 9).

for 345: 3 + 4 +5 = 12

for 12: 1 + 2 = 3

which is not 9, so 345 is not divisible by 9. (The remainder when 345 is divided by 9 is 3.)

3 + 4 + 5 = 12 which is not divisible by 9, so 345 is not divisible by 9.

345 is not divisible by 9. A quick rule for checking to see if a number is divisible by 9 is to add all of the number's digits. If their sum is divisible by 9, so is the number.2+3+4 = 9, which is divisible by 9, so 234 is divisible by 9. (234/9 = 16)3+4+5 = 123, which is not divisible by 9, so 345 is not divisible by 9 (345/9 = 38 r 3)5+6+7 = 18, which is divisible by 9, so 567 is divisible by 9 (567/9 = 63)

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.

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.)

345 nanometers = 345 x 10-9 meters.

No - any number divisible by 9 will have the sum of its digits divisible by 9.

81: 8 + 1 = 9 which is divisible by 9, so 81 is divisible by 9 162: 1 + 6 + 2 = 9 which is divisible by 9, so 162 is divisible by 9 199: 1 + 9 + 9 = 19 → 1 + 9 = 10 → 1 + 0 = 1 which is not divisible by 9, so 199 is not divisible by 9. 1125: 1 + 1 + 2 + 5 = 9 which is divisible by 9, so 1125 is divisible by 9. So 199 is the only one not divisible by 9.
