The divisibility test for the number 9 is: Any number whose digits add up to 9 or a multiple of 9, is divisible by 9. Any other number the sum of whose digits do not add up to 9 or a multiple of 9, are not divisible by 9.
For example, the digits of 81 sum up to 9, and therefore, 81 is divisible by 9. The digits of the number 319381482 add up to 39, and therefore, 319381482 is divisible by 9.

How many numbers are divisible by 9 between 5 and 1000?
111 numbers between 5 and 1000 are divisible by 9
Are all numbers divisible by 9 also divisible by 3?
Yes. Test a couple numbers divisible by 9--27, 81--and they are all divisible by 3.
What numbers are divisible by 621?
621 is divisible by 9?
What is the relationship between numbers divisible by 9 and 3?
Any that are divisible by 9 are also divisible by 3.
How many numbers between 1 and 100 inclusive are divisible by 9 or 4?
To find the numbers between 1 and 100 inclusive that are divisible by either 9 or 4, we first determine how many numbers are divisible by 9 and how many are divisible by 4. There are 11 numbers divisible by 9 (9, 18, 27, ..., 99) and 25 numbers divisible by 4 (4, 8, 12, ..., 100). However, we must be careful not to double-count numbers divisible by both 9 and 4 (36, 72). Therefore, the total number of numbers divisible by 9 or 4 between 1 and 100 inclusive is 11 + 25 - 2 = 34.
Are all numbers divisible by 3 also by 9 give example?
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.
Are all numbers that are divisible by 9 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 1000?
111 numbers between 5 and 1000 are divisible by 9
What are the divisible numbers for 9?
Nine is divisible by 1, 3 and 9.
Are all numbers divisible by 9 also divisible by 3?
Yes. Test a couple numbers divisible by 9--27, 81--and they are all divisible by 3.
What numbers divisible by 9?
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)
Are all numbers that are divisible by 9 also divisible by 3 are all numbers that are divisible by 3 also divisible by 9 how do you know?
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.
Are all numbers divisible by 9 also divisible by 4?
no, 18 is divisible by 9 but not by 4.
What numbers in between 49 and 95 are divisible by 35 and 9?
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.
What numbers are divisible by 621?
621 is divisible by 9?
Which numbers are divisible by 9 but not divisible by 3?
They are infinite.
What are the divisibility rules for 1 2 3 4 5 6 9 and 10?
All whole numbers are divisible by 1. Numbers are divisible by 2 if they end in 2, 4, 6, 8 or 0. Numbers are divisible by 3 if the sum of their digits is divisible by 3. Numbers are divisible by 4 if the last two digits of the number are divisible by 4. Numbers are divisible by 5 if the last digit of the number is either 5 or 0. Numbers are divisible by 6 if they are divisible by 2 and 3. Numbers are divisible by 9 if the sum of their digits is equal to 9 or a multiple of 9. Numbers are divisible by 10 if the last digit of the number is 0.
