To estimate the sum of these three numbers, you can round each number to the nearest whole number and then add them together. Here's how:

1. Round each number:
- 120.3 rounds to 120
- 26.4 rounds to 26
- 34.9 rounds to 35

2. Add the rounded numbers together:
- 120 + 26 + 35 = 181

So, the best estimate of the sum of 120.3, 26.4, and 34.9 is 181.
