    The LCM of 3 and 12 is 12.


    step 4 Write the fractions 9/3 and 8/12 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
    =9/3-8/12
    =(9 x 12)/(3 x 12)-(8 x 12)/(12 x 12)


    step 5 Simplify the expression to have common denominator:
    =36/12-8/12


    step 6 Take the common values out and rewrite the above expression like the below:
    =1/12 x (36/1-8/1)
    =1/12 x (36 - 8)


    step 7Simplify the above expression further:
    =1/12 x 28
    = 28/12
    =7/3
    9/3-8/12=7/3

    Hence,
    9/3 minus 8/12 equals to 7/3 in fraction.



    Problem and Workout - Cross Multiplication Method
    step 1 Observe the input parameters and what to be found:
    Input:
    Fraction A: 9/3
    Fraction B: 8/12

    What to be found?
    9/3-8/12 = ?
    Find what's the difference between 9/3 and 8/12.

    step 2 Find the product of numerator of Fraction A and denominator of Fraction B (9 x 12), find the product of numerator of Fraction B and denominator of Fraction A (8 x 3), and find the product of both denominators of Fraction A and Fraction B (3 x 12) and rewrite the equation as like the below:
    = (9 x 12) - (8 x 3)/(3 x 12)

    step 3 Simplify and rewrite the fraction:
    = (108 - 24)/36
    = 84/36
    = 7/3
