Answer 2

1 must be added to 581173 to make it exactly divisible by 11.

Step-by-step explanation:

Consider the provided information.

The Divisible test for 11 is:

If the difference between the sum of the odd-numbered digits and the sum of the even-numbered digits, counted from right to left, is divisible by 11, then the number is divisible by 11.

Now,  consider the number.
