    What is 3/8 minus 1/12 as a fraction?

    step 1 Observe the input parameters and what to be found:
    Input:
    Fraction A: 3/8
    Fraction B: 1/12

    What to be found?
    3/8-1/12 = ?
    Find what's the difference between 3/8 and 1/12.


    step 2 Compare the denominators of fractions 3/8 and 1/12 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 3/8 and 1/12 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 3/8 and 1/12:
    The LCM of 8 and 12 is 24.


    step 4 Write the fractions 3/8 and 1/12 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
    =3/8-1/12
    =(3 x 24)/(8 x 24)-(1 x 24)/(12 x 24)


    step 5 Simplify the expression to have common denominator:
    =9/24-2/24


    step 6 Take the common values out and rewrite the above expression like the below:
    =1/24 x (9/1-2/1)
    =1/24 x (9 - 2)


    step 7Simplify the above expression further:
    =1/24 x 7
    =7/24
    3/8-1/12=7/24

    Hence,
    3/8 minus 1/12 equals to 7/24 in fraction.



    Problem and Workout - Cross Multiplication Method
    step 1 Observe the input parameters and what to be found:
    Input:
    Fraction A: 3/8
    Fraction B: 1/12

    What to be found?
    3/8-1/12 = ?
    Find what's the difference between 3/8 and 1/12.

    step 2 Find the product of numerator of Fraction A and denominator of Fraction B (3 x 12), find the product of numerator of Fraction B and denominator of Fraction A (1 x 8), and find the product of both denominators of Fraction A and Fraction B (8 x 12) and rewrite the equation as like the below:
    = (3 x 12) - (1 x 8)/(8 x 12)

    step 3 Simplify and rewrite the fraction:
    = (36 - 8)/96
    = 28/96
    = 7/24
    3/8-1/12 = 7/24
    Hence,
    3/8 minus 1/12 = 7/24
