    Look at the first fraction 12/11

    Find the denominator which is 11
    Find denominator of second fraction which is 77

    What do you multiply 11 by to get 77?

    You multiply 11 by 7 to get 77

    Whatever you do to the denominator you do do the numerator.

    So 12*7 = 84

    Equivalent fraction of 12/11 = 84/77

    To check your answer divide 12 by 11 and 84 by 77, you should get the same answer.

    Hope this helps.
