The sum of the factors are divisible by 9.
Ex:
738
7+3+8=18
18/9=2
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.
The rule to decide if a number is divisible by 9 is to look at the sum of the digits. If the sum of the digits is divisible by 9, then so is the number.
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.
ANSWER:The numbers that are divisible by 9 are the numbers whose sum of the digits is a multiple of 9Example:27 = 2 + 7 = 9 (9 is a multiple of 9 thus 27 is divisible by 9)99 = 9 + 9 = 18 (18 is a multiple of 9 thus 99 is divisible by 9)
If you add up the digits, and the sum is divisible by 9 or a multiple of 9.* * * * *For really big numbers you may need to find the digital root (sum of digits) of the digital root.The divisibility rule for 9 is that the sum of the digits of a number must add up to 9 or a multiple of 9.For example, is 81 divisible by 9? Lets find out! 8+1=9. Then it is divisible by 9.
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.
How many numbers are divisible by 9 between 5 and 1000²
Nine is divisible by 1, 3 and 9.
The rule to decide if a number is divisible by 9 is to look at the sum of the digits. If the sum of the digits is divisible by 9, then so is the number.
Yes. Test a couple numbers divisible by 9--27, 81--and they are all divisible by 3.

no, 18 is divisible by 9 but not by 4.
There are no such numbers. The only number in the range that is divisible by 35 is 70 and that is not divisible by 9.
