Answer 2

Answer:

If the sum of the digits of a number is divisible by 9, then the number is divisible by 9. Some examples of numbers divisible by 9 are as follows. The number 51984 is divisible by 9 because the sum of its digits 5+1+9+8+4=27 is divisible by 9.Divisibility by:

If the last digit is even, the number is divisible by 2. If the sum of the digits is divisible by 3, the number is also. If the last two digits form a number divisible by 4, the number is also. If the last digit is a 5 or a 0, the number is divisible by 5.A number is divisible by 9, if the sum is a multiple of 9 or if the sum of its digits is divisible by 9. Consider the following numbers which are divisible by 9, using the test of divisibility by 9: 99, 198, 171, 9990, 3411. Sum of the digits of 99 = 9 + 9 = 18, which is divisible by 9.
