To find the difference between the largest 3-digit odd number and the smallest 3-digit number, we need to identify these two numbers first and then calculate the difference between them.
1. Identify the largest 3-digit odd number:
- The largest 3-digit number is 999. Since 999 is an odd number, it is also the largest 3-digit odd number.
2. Identify the smallest 3-digit number:
- The smallest 3-digit number is 100.
3. Calculate the difference between the largest 3-digit odd number and the smallest 3-digit number:
- We subtract the smallest 3-digit number from the largest 3-digit odd number.

999 - 100 = 899

Therefore, the difference between the largest 3-digit odd number and the smallest 3-digit number is 899.
