    What is 8/10 minus 1/8 as a fraction?

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

    What to be found?
    8/10-1/8 = ?
    Find what's the difference between 8/10 and 1/8.


    step 2 Compare the denominators of fractions 8/10 and 1/8 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 8/10 and 1/8 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 8/10 and 1/8:
    The LCM of 10 and 8 is 40.


    step 4 Write the fractions 8/10 and 1/8 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
    =8/10-1/8
    =(8 x 40)/(10 x 40)-(1 x 40)/(8 x 40)


    step 5 Simplify the expression to have common denominator:
    =32/40-5/40


    step 6 Take the common values out and rewrite the above expression like the below:
    =1/40 x (32/1-5/1)
    =1/40 x (32 - 5)


    step 7Simplify the above expression further:
    =1/40 x 27
    =27/40
    8/10-1/8=27/40

    Hence,
    8/10 minus 1/8 equals to 27/40 in fraction.



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

    What to be found?
    8/10-1/8 = ?
    Find what's the difference between 8/10 and 1/8.

    step 2 Find the product of numerator of Fraction A and denominator of Fraction B (8 x 8), find the product of numerator of Fraction B and denominator of Fraction A (1 x 10), and find the product of both denominators of Fraction A and Fraction B (10 x 8) and rewrite the equation as like the below:
    = (8 x 8) - (1 x 10)/(10 x 8)

    step 3 Simplify and rewrite the fraction:
    = (64 - 10)/80
    = 54/80
    = 27/40
    8/10-1/8 = 27/40
    Hence,
    8/10 minus 1/8 = 27/40
