Question

Use rounding or compatible numbers to estimate the sum 302+412

Answer 1

well i just looking at the first numbers of each one and added those up that became 700 and since the numbers behind them arent so big it rounds out to 700:))

Answer 2

i think it would be 710 because you can round the 302 to 300 and then 412 to 410 and then you add the but it asks to estimate so it would probably be 700
