Reasonableness Sun-Yi estimated 270+146 and got 300. Is her estimate resonable? Explain.

No. 270 is almost 300, and 146 is over 100 more. A better estimate would have been 400.

Me don’t know lol I stupid

Hmmmm No. Round 146 to 150 and add both 270 and 150. It's 420. So 400 would be more reasonable. 300 is not reasonable because it ain't close. (Not my idea just found it not my answer!!!)

No me no no

I do not know

AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA

no

Idek

No, not at all. 270 is already close to 300 so with a hundred it would be in 300 but the tens and ones would make another, 400 is a closer estimate

Yes because uwu
