Estimate the sum by rounding each number to the nearest hundred and then adding.929 + 89The sum is approximately .
Solution
-
First, round each number to the nearest hundred.
- 929 rounds up to 1000 because it's closer to 1000 than to 900.
- 89 rounds down to 100 because it's closer to 100 than to 0.
-
Then, add the rounded numbers together.
- 1000 + 100 = 1100
So, the sum of 929 and 89, when both numbers are rounded to the nearest hundred, is approximately 1100.
