To round each number to the nearest hundred:
- 37.82 rounds to 0 (since it is less than 100),
- 45.6 also rounds to 0 (since it is less than 100).
Now, we can rewrite the problem with the estimates:
Estimate:
0 + 0
Answer:
0
So, the estimated sum of 37.82 + 45.6, when rounding to the nearest hundreds place, is 0.
