how can you use rounding to estimate 331+193
331+193
This depends on whether you're rounding to the nearest 10 or 100. If rounding to the nearest 10, 331 rounds to 330 and 193 rounds to 190, so then you'd do 330+190. If rounding to the nearest 100, 330 rounds to 300 and 190 rounds to 200, so then you'd do 300+200.
I'd add 330 and 200. Others might add 330 and 190.
To use rounding to estimate the sum of 331 and 193, you can follow these steps:
Step 1: Round each number to the nearest ten.
- 331 rounds to 330
- 193 rounds to 190
Step 2: Add the rounded numbers together.
- 330 + 190 = 520
Therefore, using rounding to estimate, the sum of 331 and 193 is approximately 520.
