    What is 4/5 minus 3/10 as a fraction?

    step 1 Observe the input parameters and what to be found:
    Input:
    Fraction A: 4/5
    Fraction B: 3/10

    What to be found?
    4/5-3/10 = ?
    Find what's the difference between 4/5 and 3/10.


    step 2 Compare the denominators of fractions 4/5 and 3/10 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 4/5 and 3/10 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 4/5 and 3/10:
    The LCM of 5 and 10 is 10.


    step 4 Write the fractions 4/5 and 3/10 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
    =4/5-3/10
    =(4 x 10)/(5 x 10)-(3 x 10)/(10 x 10)


    step 5 Simplify the expression to have common denominator:
    =8/10-3/10


    step 6 Take the common values out and rewrite the above expression like the below:
    =1/10 x (8/1-3/1)
    =1/10 x (8 - 3)


    step 7Simplify the above expression further:
    =1/10 x 5
    = 5/10
    =1/2
    4/5-3/10=1/2

    Hence,
    4/5 minus 3/10 equals to 1/2 in fraction.



    Problem and Workout - Cross Multiplication Method
    step 1 Observe the input parameters and what to be found:
    Input:
    Fraction A: 4/5
    Fraction B: 3/10

    What to be found?
    4/5-3/10 = ?
    Find what's the difference between 4/5 and 3/10.

    step 2 Find the product of numerator of Fraction A and denominator of Fraction B (4 x 10), find the product of numerator of Fraction B and denominator of Fraction A (3 x 5), and find the product of both denominators of Fraction A and Fraction B (5 x 10) and rewrite the equation as like the below:
    = (4 x 10) - (3 x 5)/(5 x 10)

    step 3 Simplify and rewrite the fraction:
    = (40 - 15)/50
    = 25/50
    = 1/2
    4/5-3/10 = 1/2
    Hence,
    4/5 minus 3/10 = 1/2
