## mariposa1415 2 years ago Estimate the sum of 9.327 + 5.72 + 4.132 to one decimal place.

1. northmass

19.2

2. ucreategames

the estimate problem is 9.3+5.8+4.1\ and the estimated answer is 19.2

3. ucreategames

come on

4. mariposa1415

thx

5. CliffSedge

Wouldn't the 5.72 round to 5.7, @ucreategames ?

6. ucreategames

oops i meant that

7. CliffSedge

Rounding it up actually gives a more accurate answer, but doing so without explaining why might confuse @mariposa1415 .

8. ucreategames

so the estimated answer is 19.1

9. CliffSedge

I think that would more correctly answer the question the way it was asked, though there are other ways to estimate. For example, rounding one number up and rounding the other number down cancels some of the rounding error. If you round all the numbers down then the estimate will necessarily under-represent the actual sum. *shrug*

oh

11. mariposa1415

The sum of 9.327 +5.72+ 4.132 is 19.179 and the estimate answer is 19.1.

12. mariposa1415
