What is the smallest 6-digit number that is exactly divisible by 111?
Answer: D
The smallest 6-digit number is 100,000.
To find the smallest 6-digit number divisible by 111, we divide 100,000 by 111.
\(100000 \div 111\) gives a quotient of 900 and a remainder of 100.
The number to be added to 100,000 to make it divisible by 111 is \((111 - \text{remainder}) = 111 - 100 = 11\).
So, the required number is \(100,000 + 11 = 100,011\).
