    What is 9/8 minus 9/10 as a fraction?

    step 1 Observe the input parameters and what to be found:
    Input:
    Fraction A: 9/8
    Fraction B: 9/10

    What to be found?
    9/8-9/10 = ?
    Find what's the difference between 9/8 and 9/10.


    step 2 Compare the denominators of fractions 9/8 and 9/10 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 9/8 and 9/10 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 9/10:
    The LCM of 8 and 10 is 40.


    step 4 Write the fractions 9/8 and 9/10 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
    =9/8-9/10
    =(9 x 40)/(8 x 40)-(9 x 40)/(10 x 40)


    step 5 Simplify the expression to have common denominator:
    =45/40-36/40


    step 6 Take the common values out and rewrite the above expression like the below:
    =1/40 x (45/1-36/1)
    =1/40 x (45 - 36)


    step 7Simplify the above expression further:
    =1/40 x 9
    =9/40
    9/8-9/10=9/40

    Hence,
    9/8 minus 9/10 equals to 9/40 in fraction.



    Problem and Workout - Cross Multiplication Method
    step 1 Observe the input parameters and what to be found:
    Input:
    Fraction A: 9/8
    Fraction B: 9/10

    What to be found?
    9/8-9/10 = ?
    Find what's the difference between 9/8 and 9/10.

    step 2 Find the product of numerator of Fraction A and denominator of Fraction B (9 x 10), find the product of numerator of Fraction B and denominator of Fraction A (9 x 8), and find the product of both denominators of Fraction A and Fraction B (8 x 10) and rewrite the equation as like the below:
    = (9 x 10) - (9 x 8)/(8 x 10)

    step 3 Simplify and rewrite the fraction:
    = (90 - 72)/80
    = 18/80
    = 9/40
    9/8-9/10 = 9/40
    Hence,
    9/8 minus 9/10 = 9/40
