    1/12 - 1/3 as a fraction provides the detailed information about what is 1/12 minus 1/3 in fraction and decimal form, and the answer with steps to understand how it is being calculated by using different methods.

    1/12-1/3 equals to
    1/12 - 1/3 = (?)
    1/12 - 1/3 = [(1 x 3) - (1 x 12)]/(12 x 3)
    = (3 - 12)/36
    = -9/36
    = (9 x -1)/(9 x 4)
    = -1/4
    1/12 - 1/3 = -1/4
    1/12 minus 1/3 is equal to -1/4

    where
    1/12 is a fraction as a minuend,
    1/3 is a fraction as a subtrahend,
    -1/4 is the difference between 1/12 and 1/3.

    1/12 minus 1/3 as a decimal
    1/12 - 1/3 = -1/4
    -1/4 = -0.25
    1/12-1/3 as a decimal is -0.25
    where
    -0.25 is the difference between 1/12 and 1/3.

    Problem and Workout - LCM Method:
    What is 1/12 minus 1/3 as a fraction?

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

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


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


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


    step 5 Simplify the expression to have common denominator:
    =1/12-4/12


    step 6 Take the common values out and rewrite the above expression like the below:
    =1/12 x (1/1-4/1)
    =1/12 x (1 - 4)


    step 7Simplify the above expression further:
    =1/12 x -3
    = -3/12
    =-1/4
    1/12-1/3=-1/4

    Hence,
    1/12 minus 1/3 equals to -1/4 in fraction.



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

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

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

    step 3 Simplify and rewrite the fraction:
    = (3 - 12)/36
    = -9/36
    = -1/4
    1/12-1/3 = -1/4
    Hence,
    1/12 minus 1/3 = -1/4
