    The LCM of 8 and 9 is 72.


    step 4 Write the fractions 7/8 and 1/9 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
    =7/8-1/9
    =(7 x 72)/(8 x 72)-(1 x 72)/(9 x 72)


    step 5 Simplify the expression to have common denominator:
    =63/72-8/72


    step 6 Take the common values out and rewrite the above expression like the below:
    =1/72 x (63/1-8/1)
    =1/72 x (63 - 8)


    step 7Simplify the above expression further:
    =1/72 x 55
    =55/72
    7/8-1/9=55/72

    Hence,
    7/8 minus 1/9 equals to 55/72 in fraction.



    Problem and Workout - Cross Multiplication Method
    step 1 Observe the input parameters and what to be found:
