Estimate the quotient.
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?

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

Why did you use 400?

5th grade math  elizabeth, Wednesday, April 9, 2014 at 10:27pm
I should have said 240/80=3 because 400 is not close to 255.

Yes. That's much better. :)
