Estimate this question using compatible numbers. 276÷ 42

Answers

Answer 1

Answer: We are estimating, so we round the numbers to something that would be beneficial to us to more easily solve the problem (using mental math). We want to round to compatible numbers to make the math more simple. If we round to numbers that are divisible by 10 it makes the association easy to see... If we round 276 to 280 and 42 to 40, we see that we have complimentary numbers because 28 divides evenly by 4 to give 7. So

280 / 40 = 7

Well, the top part factors into (x - 4) * (x + 3).

So, we have this:

(x - 4) (x + 3)/ (x + 3)

We know that the (x + 3)s can cancel out and we're left with (x - 4) as our answer. If there are any questions then leave a comment. Good luck!

16000.
You just need to take the numbers in the thousands place and left, and if the numbers on the right are greater than 500, you round up. In this case, 311 is less than 500 so you round down and get 16000.
