Question

which is a good comparison of the estimated sum and the actual sum of 7 10/12+2 11/12? Greater or lesser

Answer 1

I would estimate 7 10/12 to 8 and i would estimate 2 11/12 to  3 so 8 plus 3 would equal 11 so that would be the estimate. the actual would be 10 8/11 so the estimate would be bigger.
