To round each number to the nearest hundred:
- 48,132 rounds to 48,100 (because the tens digit is 3, which is less than 5).
- 32,884 rounds to 32,900 (because the tens digit is 8, which is 5 or more).
Now, you can estimate the sum:
48,100 + 32,900 = 81,000
So, the completed equation using the rounded values is:
48,100 + 32,900 = 81,000.
