Answer 2

Given:

A number 9999999925 is divided by 9.

To Find:

The remainder of the above mathematical operation is?

Solution:

1. The given number is 9999999925, it is divided by 9.

2. A number is said to be divisible by 9 if the sum of the digits of the number is a multiple of 9.

For example, the number 927 is divisible by 9 because the sum of the digits of the number is 18 which is a multiple of 9.

3. The number 9999999925 has the sum of the digits 79 which is not a multiple of 9. Hence the number is not perfectly divisible by 9.

4. The given number can be also written as,

=> 9999999925 = 9000000000 + 900000000 + 90000000 + 9000000 + 900000 + 90000 + 9000 + 900 + 25,

=> Simplifying further,

=> 9999999925 = 9(1000000000) + 9(100000000) + 9(10000000) + 9(1000000) + 9(100000) + 9(10000) + 9(1000) + 9(100) + 25,

5. The number 25 can be written as,

=> 25 = 9(2) + 7.

=> 9999999925 = 9(1000000000) + 9(100000000) + 9(10000000) + 9(1000000) + 9(100000) + 9(10000) + 9(1000) + 9(100) + 9(2) + 7,

=> Taking 9 common,

=> 9999999925 = 9(1111111102) + 7,

6. The remainder is 7 and the quotient is 1111111102.

Therefore, the remainder when the number 9999999925 is divided by 9 is 7.
