    What is 9/8 minus 3/5 as a fraction?

    step 1 Observe the input parameters and what to be found:
    Input:
    Fraction A: 9/8
    Fraction B: 3/5

    What to be found?
    9/8-3/5 = ?
    Find what's the difference between 9/8 and 3/5.


    step 2 Compare the denominators of fractions 9/8 and 3/5 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 9/8 and 3/5 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 9/8 and 3/5:
    The LCM of 8 and 5 is 40.


    step 4 Write the fractions 9/8 and 3/5 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
    =9/8-3/5
    =(9 x 40)/(8 x 40)-(3 x 40)/(5 x 40)


    step 5 Simplify the expression to have common denominator:
    =45/40-24/40


    step 6 Take the common values out and rewrite the above expression like the below:
    =1/40 x (45/1-24/1)
    =1/40 x (45 - 24)


    step 7Simplify the above expression further:
    =1/40 x 21
    =21/40
    9/8-3/5=21/40

    Hence,
    9/8 minus 3/5 equals to 21/40 in fraction.
