    The LCM of 8 and 7 is 56.


    step 4 Write the fractions 7/8 and 2/7 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
    =7/8-2/7
    =(7 x 56)/(8 x 56)-(2 x 56)/(7 x 56)


    step 5 Simplify the expression to have common denominator:
    =49/56-16/56


    step 6 Take the common values out and rewrite the above expression like the below:
    =1/56 x (49/1-16/1)
    =1/56 x (49 - 16)


    step 7Simplify the above expression further:
    =1/56 x 33
    =33/56
    7/8-2/7=33/56

    Hence,
    7/8 minus 2/7 equals to 33/56 in fraction.
