The Rule for 9: The prime factors of 9 are 3 and 3. So we can use a very similar rule to determine if a number is divisible by 9. Basically, we will see if the sum of the digits is divisible by 9. If it is, then the actual number is also divisible by 9.

Answer 2

Hi, the divisibility rule of 9 is the sum of the digits.

24 is not in the table of 9

Therefore 5496 is not divisible by 9.

Hope you understood;)
