To determine if 1011 is divisible by each of these numbers:
- It is not divisible by 2, as it is odd.
- It is not divisible by 5 or 10, as it does not end in 0 or 5.
- For 3, the sum of the digits (1+0+1+1=3) is divisible by 3, so 1011 is divisible by 3.
- For 9, the sum of the digits is also divisible by 9, so it is not divisible by 9.
In summary, 1011 is only divisible by 3.
