Which of the following represents the most accurate estimation of 5+4

Well 5+4=9 so the answer should be somewhere around 9

Hi there! ~

Even though this question is incomplete, we can still try and find our given answer.

If we have "estimation" it means, to the nearest, or estimate the answer.

Now 5+4=9

But if we are estimating, it could be rounded to 10.
