    Your answer is ...

    First,

    we have to turn our mixed fractions into an improper fraction.

    =4 1/8 which is 33/8 (4 x 8 + 1).

    Our next mixed fraction,

    we have 1 1/7 which is 8/7 (1 x 7 + 1).

    Now, we have the get the same denominator in order to subtract.

    SO, both 8 and 7 goes in to 56. So we multiply both mixed fractions to get the same denominator.

    (Tip: what ever you do to do numerator, you do to the denominator; and the other way around).

    33/8 : 33*7=231 and our denominator, 8*7=56

    So our improper fraction now,

    231/56

    Our next fraction 8/7,

    7*8 = 56 and our numerator 8*8=64.

    =64/56

    So, now we subtract.

    231-64 = 167 and our common denominator. 167/56

    Now we divide 167 by 56 which is 2 and remainder is 55.

    So, you should end up with a mixed fraction, 2 55/56.
