Question

what is the divisibility test of 9​

Answer 1

Divisibility Rule of 9

That is, if the sum of digits of the number is divisible by 9, then the number itself is divisible by 9. Example: Consider 78532, as the sum of its digits (7+8+5+3+2) is 25, which is not divisible by 9, hence 78532 is not divisible by 9.

Answer 2

Answer:

The divisibility test of 9 states that the number should be divisible by 3 by doing the test of divisibility by 3.

For eg : 403 = 4+ 0+ 3 ( 7)

7 is not divisible by 3

Therefore, 403 is not divisible by 9
