Estimate the quotient.

Question

1.175/18

2. 231/37

My answer is 1. 200/20=10
2. 200/40=5

Did I find the correct estimates for these problems?

Answer 1

Yes. Good job!

Answer 2

Thanks. For 255/81, my answer is 400/80=5. Do I have correct answer?

Answer 3

Why did you use 400?

Answer 4

I should have said 240/80=3 because 400 is not close to 255.

Answer 5

Yes. That's much better. :-)
