    3/4 - 1/2 as a fraction provides the detailed information about what is 3/4 minus 1/2 in fraction and decimal form, and the answer with steps to understand how it is being calculated by using different methods.

    3/4-1/2 equals to
    3/4 - 1/2 = (?)
    3/4 - 1/2 = [(3 x 2) - (1 x 4)]/(4 x 2)
    = (6 - 4)/8
    = 2/8
    = (2 x 1)/(2 x 4)
    = 1/4
    3/4 - 1/2 = 1/4
    3/4 minus 1/2 is equal to 1/4

    where
    3/4 is a fraction as a minuend,
    1/2 is a fraction as a subtrahend,
    1/4 is the difference between 3/4 and 1/2.

    3/4 minus 1/2 as a decimal
    3/4 - 1/2 = 1/4

    Problem and Workout - LCM Method:
    What is 3/4 minus 1/2 as a fraction?

    step 1 Observe the input parameters and what to be found:
    Input:
    Fraction A: 3/4
    Fraction B: 1/2

    What to be found?
    3/4-1/2 = ?
    Find what's the difference between 3/4 and 1/2.


    step 2 Compare the denominators of fractions 3/4 and 1/2 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 3/4 and 1/2 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 3/4 and 1/2:
    The LCM of 4 and 2 is 4.


    step 4 Write the fractions 3/4 and 1/2 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
    =3/4-1/2
    =(3 x 4)/(4 x 4)-(1 x 4)/(2 x 4)


    step 5 Simplify the expression to have common denominator:
    =3/4-2/4


    step 6 Take the common values out and rewrite the above expression like the below:
    =1/4 x (3/1-2/1)
    =1/4 x (3 - 2)


    step 7Simplify the above expression further:
    =1/4 x 1
    =1/4
    3/4-1/2=1/4

    Hence,
    3/4 minus 1/2 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: 3/4
    Fraction B: 1/2

    What to be found?
    3/4-1/2 = ?
    Find what's the difference between 3/4 and 1/2.

    step 2 Find the product of numerator of Fraction A and denominator of Fraction B (3 x 2), find the product of numerator of Fraction B and denominator of Fraction A (1 x 4), and find the product of both denominators of Fraction A and Fraction B (4 x 2) and rewrite the equation as like the below:
    = (3 x 2) - (1 x 4)/(4 x 2)

    step 3 Simplify and rewrite the fraction:
    = (6 - 4)/8
    = 2/8
    = 1/4
    3/4-1/2 = 1/4
    Hence,
    3/4 minus 1/2 = 1/4
