    7 9/12 = 7.75

    2 11/12 = 2.917

    So we ca round both of these up.

    7.75 rounds to 8

    2.917 rounds to 3

    8 + 3 = 11

    So the estimated sun is 11.

    7 9/12 + 2 11/12 = 10 2/3

    So the actual sum is 10 2/3.

    The estimated sum is a pretty good estimate to the original number.
