None is divisible by all those.
Nothing - as there is no number that goes into both 9 and 40. Only 1 or 3 goes into 9, and 40 is not divisible by 3 (either 39 or 42 are nearest). So it stays at 9 / 40

NO. 1110 is not divisible by 9. A number is divisible by 9 if the sum of its digits is divisible by 9. 1110 = 1 + 1 + 1 + 0 = 3 (3 is not divisible by 9, thus, 1110 is not divisible by 9.)
There are 11 divisible by 9 (which are 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99); There are 9 (or 10) divisible by 10 (which are 10, 20, 30, 40, 50, 60, 70, 80, 90; and 100 if it is 1 to 100 inclusive); There is 1 divisible by both 9 and 10 (which is 90).
40 is divisible by 5 and 10, but not by 9 because 40 is a multiple of 5 and 10 but not of 9.
Yes 40
The numbers between 40 and 60 that are divisible by 9 are 45 and 54. 45/9=5 and 54/9=6. The sum of 45 and 54 is 99.

NO. 1110 is not divisible by 9. A number is divisible by 9 if the sum of its digits is divisible by 9. 1110 = 1 + 1 + 1 + 0 = 3 (3 is not divisible by 9, thus, 1110 is not divisible by 9.)
There are 11 divisible by 9 (which are 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99); There are 9 (or 10) divisible by 10 (which are 10, 20, 30, 40, 50, 60, 70, 80, 90; and 100 if it is 1 to 100 inclusive); There is 1 divisible by both 9 and 10 (which is 90).
81: 8 + 1 = 9 which is divisible by 9, so 81 is divisible by 9 162: 1 + 6 + 2 = 9 which is divisible by 9, so 162 is divisible by 9 199: 1 + 9 + 9 = 19 → 1 + 9 = 10 → 1 + 0 = 1 which is not divisible by 9, so 199 is not divisible by 9. 1125: 1 + 1 + 2 + 5 = 9 which is divisible by 9, so 1125 is divisible by 9. So 199 is the only one not divisible by 9.
All numbers divisible by 3 are NOT divisible by 9. As an example, 6, which is divisible by 3, is not divisible by 9. However, all numbers divisible by 9 are also divisible by 3 because 9 is divisible by 3.
