Question

Estimate the sum to the nearest whole number. 29.1 + 78.9 + 41.5

Answer 1

To estimate the sum of 29.1, 78.9, and 41.5 to the nearest whole number, we can round each number:

- 29.1 rounds to 29
- 78.9 rounds to 79
- 41.5 rounds to 42

Now we can add the rounded numbers:

29 + 79 + 42 = 150

So, the estimated sum to the nearest whole number is **150**.
