make an estimate by rounding to the nearest hundreds place. Rewrite the problem with your estimate and answer.

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.
