    What is 9/11 minus 8/10 as a fraction?

    step 1 Observe the input parameters and what to be found:
    Input:
    Fraction A: 9/11
    Fraction B: 8/10

    What to be found?
    9/11-8/10 = ?
    Find what's the difference between 9/11 and 8/10.


    step 2 Compare the denominators of fractions 9/11 and 8/10 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 9/11 and 8/10 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 9/11 and 8/10:
    The LCM of 11 and 10 is 110.


    step 4 Write the fractions 9/11 and 8/10 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
    =9/11-8/10
    =(9 x 110)/(11 x 110)-(8 x 110)/(10 x 110)


    step 5 Simplify the expression to have common denominator:
    =90/110-88/110


    step 6 Take the common values out and rewrite the above expression like the below:
    =1/110 x (90/1-88/1)
    =1/110 x (90 - 88)


    step 7Simplify the above expression further:
    =1/110 x 2
    = 2/110
    =1/55
    9/11-8/10=1/55

    Hence,
    9/11 minus 8/10 equals to 1/55 in fraction.



    Problem and Workout - Cross Multiplication Method
    step 1 Observe the input parameters and what to be found:
    Input:
    Fraction A: 9/11
    Fraction B: 8/10

    What to be found?
    9/11-8/10 = ?
    Find what's the difference between 9/11 and 8/10.

    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 (8 x 11), and find the product of both denominators of Fraction A and Fraction B (11 x 10) and rewrite the equation as like the below:
    = (9 x 10) - (8 x 11)/(11 x 10)

    step 3 Simplify and rewrite the fraction:
    = (90 - 88)/110
    = 2/110
    = 1/55
    9/11-8/10 = 1/55
    Hence,
    9/11 minus 8/10 = 1/55
