    3-7/6-11/12

    Find the common denominator which is 12

    Pretend that there is a 1 for 3.

    Multiply by 12 for 3/1

    3 (12) / 1 (12) = 36/12

    Multiply by 2 for 7/6

    7 (2) / 6 (2) = 14/12

    36/12-14/12-11/12

    22/12-11/12

    =11/12

    Answer: 11/12

    11/12

    Step-by-step explanation:

    we have:

    3-7/6-11/12

    3-7/6 = (18-7) / 6 = 11/6

    so we have:

    11/6-11/12 = (132-66) / 72

    (132-66) / 72 = 66/72

    finally we have:

    66/72 = 11/12
