How do you find a range to estimate each sum

388+192+741
Thank you.

estimate:

388 is 400
192 is 200
741 is 700
add: estimate is 1300

Thank you. So would my range be 1200 - 1400?

That is ok.

Thanks so much.

To find a range to estimate the sum of three numbers, you can use rounding. Here's how you can do it for the given numbers:

1. Round the numbers:
- 388 rounds to 400
- 192 rounds to 200
- 741 rounds to 700

2. Add the rounded numbers together:
400 + 200 + 700 = 1,300

So, the estimated sum of 388 + 192 + 741 is 1,300.

To find a range for this estimate, you can consider the maximum and minimum values that each rounded number could be.

1. Maximum values:
- 388 could round up to 400
- 192 could round up to 200
- 741 could round down to 700

The sum of the maximum values is 400 + 200 + 700 = 1,300.

2. Minimum values:
- 388 could round down to 300
- 192 could round down to 100
- 741 could round up to 800

The sum of the minimum values is 300 + 100 + 800 = 1,200.

Therefore, the range to estimate the sum is from 1,200 to 1,300.
