How can you tell if a number is divisible by 9?
Any number which is divisible by 9 contains digits which, when added together, are equal to 9 or a multiple of 9. For example, 63 is divisible by 9 because 6 + 3 = 9. 288 is divisible by 9 because 2 + 8 + 8 = 18 and 18/9 = 2.
What makes a number divisible by 18?
The formal answer is that 18 goes into the number without remainder. A simple test for divisibility by 18 is as follows: (a) the number must be even. (b) the sum of all the digits of the number must be divisible by 9. (a) ensures the number is divisible by 2 and (b) that it is divisible by 9. So, together they ensure divisibility by 2*9 = 18. Note that (b) only works with 3 and 9.

When 9 can be divided?
Add the digits of the number. If the sum is 9 or divisible by 9, the number itself is divisible by 9. Ex: 675 6 + 7+ 5 = 18 1 + 8 = 9 675 is divisible by 9.
What largest 3 - digit number divisible by both 6 and 9?
999 is divisible by 9, but not by six; the next lower number divisible by 9 is 990, which is also divisible by 6, so that's the answer. Some shortcuts for divisibility: 0 is divisible by any number. If the last digit of a number is divisible by 2, the number itself is divisible by 2. If the sum of the digits of a number is divisible by 3, the number itself is divisible by 3. If the last TWO digits of a number are divisible by 4, the number itself is divisible by 4. If the last digit of a number is divisible by 5, the number itself is divisible by 5. If a number is divisible by both 2 and 3, it is divisible by 6. If the last THREE digits of a number are divisible by 8, the number itself is divisible by 8. If the sum of the digits of a number is divisible by 9, the number itself is divisible by 9. 990: 9+9+0=18, which is divisible by 9, so 990 is divisible by 9. 18 is also divisible by 3, so 990 is divisible by 3, and since 990 ends in 0 it's also divisible by 2, meaning that it's divisible by 6 as well.
A number divisible by 3 if the sum of the digits of the number divisible by 3?
Correct, also applies to 9.yes, example: 99/3=33 9+9=18 18/3=6
