    1/2 - 1/7 as a fraction provides the detailed information about what is 1/2 minus 1/7 in fraction and decimal form, and the answer with steps to understand how it is being calculated by using different methods.

    1/2-1/7 equals to
    1/2 - 1/7 = (?)
    1/2 - 1/7 = [(1 x 7) - (1 x 2)]/(2 x 7)
    = (7 - 2)/14
    = 5/14
    1/2 - 1/7 = 5/14
    1/2 minus 1/7 is equal to 5/14

    where
    1/2 is a fraction as a minuend,
    1/7 is a fraction as a subtrahend,
    5/14 is the difference between 1/2 and 1/7.

    1/2 minus 1/7 as a decimal
    1/2 - 1/7 = 5/14
    5/14 = 0.3571
    1/2-1/7 as a decimal is 0.3571
    where
    0.3571 is the difference between 1/2 and 1/7.

    What is 1/2 minus 1/7 as a fraction?

    step 1 Observe the input parameters and what to be found:
    Input:
    Fraction A: 1/2
    Fraction B: 1/7

    What to be found?
    1/2-1/7 = ?
    Find what's the difference between 1/2 and 1/7.


    step 2 Compare the denominators of fractions 1/2 and 1/7 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 1/2 and 1/7 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 1/2 and 1/7:
    The LCM of 2 and 7 is 14.


    step 4 Write the fractions 1/2 and 1/7 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
    =1/2-1/7
    =(1 x 14)/(2 x 14)-(1 x 14)/(7 x 14)


    step 5 Simplify the expression to have common denominator:
    =7/14-2/14


    step 6 Take the common values out and rewrite the above expression like the below:
    =1/14 x (7/1-2/1)
    =1/14 x (7 - 2)


    step 7Simplify the above expression further:
    =1/14 x 5
    =5/14
    1/2-1/7=5/14

    Hence,
    1/2 minus 1/7 equals to 5/14 in fraction.



    Problem and Workout - Cross Multiplication Method
    step 1 Observe the input parameters and what to be found:
    Input:
    Fraction A: 1/2
    Fraction B: 1/7

    What to be found?
    1/2-1/7 = ?
    Find what's the difference between 1/2 and 1/7.

    step 2 Find the product of numerator of Fraction A and denominator of Fraction B (1 x 7), find the product of numerator of Fraction B and denominator of Fraction A (1 x 2), and find the product of both denominators of Fraction A and Fraction B (2 x 7) and rewrite the equation as like the below:
    = (1 x 7) - (1 x 2)/(2 x 7)

    step 3 Simplify and rewrite the fraction:
    = (7 - 2)/14
    1/2-1/7 = 5/14
    Hence,
    1/2 minus 1/7 = 5/14
