    Problem and Workout - LCM Method:
    What is 5/2 minus 6/8 as a fraction?

    step 1 Observe the input parameters and what to be found:
    Input:
    Fraction A: 5/2
    Fraction B: 6/8

    What to be found?
    5/2-6/8 = ?
    Find what's the difference between 5/2 and 6/8.


    step 2 Compare the denominators of fractions 5/2 and 6/8 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 5/2 and 6/8 are not equal, it is said to be unlike fractions subtraction.

    step 3For unlike fractions subtraction, find the LCM (least common multiple) of both denominators of fractions 5/2 and 6/8:
    The LCM of 2 and 8 is 8.


    step 4 Write the fractions 5/2 and 6/8 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
    =5/2-6/8
    =(5 x 8)/(2 x 8)-(6 x 8)/(8 x 8)


    step 5 Simplify the expression to have common denominator:
    =20/8-6/8


    step 6 Take the common values out and rewrite the above expression like the below:
    =1/8 x (20/1-6/1)
    =1/8 x (20 - 6)


    step 7Simplify the above expression further:
    =1/8 x 14
    = 14/8
    =7/4
    5/2-6/8=7/4

    Hence,
    5/2 minus 6/8 equals to 7/4 in fraction.



    Problem and Workout - Cross Multiplication Method
    step 1 Observe the input parameters and what to be found:
    Input:
    Fraction A: 5/2
    Fraction B: 6/8

    What to be found?
    5/2-6/8 = ?
    Find what's the difference between 5/2 and 6/8.

    step 2 Find the product of numerator of Fraction A and denominator of Fraction B (5 x 8), find the product of numerator of Fraction B and denominator of Fraction A (6 x 2), and find the product of both denominators of Fraction A and Fraction B (2 x 8) and rewrite the equation as like the below:
    = (5 x 8) - (6 x 2)/(2 x 8)

    step 3 Simplify and rewrite the fraction:
    = (40 - 12)/16
    = 28/16
    = 7/4
    5/2-6/8 = 7/4
    Hence,
    5/2 minus 6/8 = 7/4
