    What is 5/9 minus 4/8 as a fraction?

    step 1 Observe the input parameters and what to be found:
    Input:
    Fraction A: 5/9
    Fraction B: 4/8

    What to be found?
    5/9-4/8 = ?
    Find what's the difference between 5/9 and 4/8.


    step 2 Compare the denominators of fractions 5/9 and 4/8 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 5/9 and 4/8 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 5/9 and 4/8:
    The LCM of 9 and 8 is 72.


    step 4 Write the fractions 5/9 and 4/8 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
    =5/9-4/8
    =(5 x 72)/(9 x 72)-(4 x 72)/(8 x 72)


    step 5 Simplify the expression to have common denominator:
    =40/72-36/72


    step 6 Take the common values out and rewrite the above expression like the below:
    =1/72 x (40/1-36/1)
    =1/72 x (40 - 36)


    step 7Simplify the above expression further:
    =1/72 x 4
    = 4/72
    =1/18
    5/9-4/8=1/18

    Hence,
    5/9 minus 4/8 equals to 1/18 in fraction.



    Problem and Workout - Cross Multiplication Method
    step 1 Observe the input parameters and what to be found:
    Input:
    Fraction A: 5/9
    Fraction B: 4/8

    What to be found?
    5/9-4/8 = ?
    Find what's the difference between 5/9 and 4/8.

    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 (4 x 9), and find the product of both denominators of Fraction A and Fraction B (9 x 8) and rewrite the equation as like the below:
    = (5 x 8) - (4 x 9)/(9 x 8)

    step 3 Simplify and rewrite the fraction:
    = (40 - 36)/72
    = 4/72
    = 1/18
    5/9-4/8 = 1/18
    Hence,
    5/9 minus 4/8 = 1/18
