Question

Multiply the largest three-digit number by the smallest three-digit number.

• A. 99999
• B. 99990
• C. 98901
• D. 99900

Answer 1

The correct option is D 99900

The smallest 3-digit number is 100.
The largest 3-digit number is 999.
Now, let us multiply.
Since this is a special case where we multiply with 100, we just need to multiply the non-zero digits and then add two zeroes at the end.

Using the conventional method, the same calculation is as follows:

Therefore, the answer is 99,900.
