    What is 3/10 minus 8/9 as a fraction?

    step 1 Observe the input parameters and what to be found:
    Input:
    Fraction A: 3/10
    Fraction B: 8/9

    What to be found?
    3/10-8/9 = ?
    Find what's the difference between 3/10 and 8/9.


    step 2 Compare the denominators of fractions 3/10 and 8/9 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 3/10 and 8/9 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 3/10 and 8/9:
    The LCM of 10 and 9 is 90.


    step 4 Write the fractions 3/10 and 8/9 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
    =3/10-8/9
    =(3 x 90)/(10 x 90)-(8 x 90)/(9 x 90)


    step 5 Simplify the expression to have common denominator:
    =27/90-80/90


    step 6 Take the common values out and rewrite the above expression like the below:
    =1/90 x (27/1-80/1)
    =1/90 x (27 - 80)


    step 7Simplify the above expression further:
    =1/90 x -53
    =-53/90
    3/10-8/9=-53/90

    Hence,
    3/10 minus 8/9 equals to -53/90 in fraction.



    Problem and Workout - Cross Multiplication Method
    step 1 Observe the input parameters and what to be found:
    Input:
    Fraction A: 3/10
    Fraction B: 8/9

    What to be found?
    3/10-8/9 = ?
    Find what's the difference between 3/10 and 8/9.

    step 2 Find the product of numerator of Fraction A and denominator of Fraction B (3 x 9), find the product of numerator of Fraction B and denominator of Fraction A (8 x 10), and find the product of both denominators of Fraction A and Fraction B (10 x 9) and rewrite the equation as like the below:
    = (3 x 9) - (8 x 10)/(10 x 9)

    step 3 Simplify and rewrite the fraction:
    = (27 - 80)/90
    3/10-8/9 = -53/90
    Hence,
    3/10 minus 8/9 = -53/90
