Question

Use rounding or compatible numbers to estimate the sum 271 + 425

Answer 1

I’m not sure how rounded you have to get but 271 would be 270 and 425 would be 430. 270+430=700

Answer 2

700

Explanation:

For this one I'll do estimates. 271 estimated would drop down to 270. And 425 would bump up to 430. Adding 270 and 400 you would get a round number of 700!

Hope this helped.
