    Problem and Workout - LCM Method:
    What is 7/10 minus 4/5 as a fraction?

    step 1 Observe the input parameters and what to be found:
    Input:
    Fraction A: 7/10
    Fraction B: 4/5

    What to be found?
    7/10-4/5 = ?
    Find what's the difference between 7/10 and 4/5.


    step 2 Compare the denominators of fractions 7/10 and 4/5 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 7/10 and 4/5 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 7/10 and 4/5:
    The LCM of 10 and 5 is 10.


    step 4 Write the fractions 7/10 and 4/5 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
    =7/10-4/5
    =(7 x 10)/(10 x 10)-(4 x 10)/(5 x 10)


    step 5 Simplify the expression to have common denominator:
    =7/10-8/10


    step 6 Take the common values out and rewrite the above expression like the below:
    =1/10 x (7/1-8/1)
    =1/10 x (7 - 8)


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

    Hence,
    7/10 minus 4/5 equals to -1/10 in fraction.



    Problem and Workout - Cross Multiplication Method
    step 1 Observe the input parameters and what to be found:
    Input:
    Fraction A: 7/10
    Fraction B: 4/5

    What to be found?
    7/10-4/5 = ?
    Find what's the difference between 7/10 and 4/5.

    step 2 Find the product of numerator of Fraction A and denominator of Fraction B (7 x 5), find the product of numerator of Fraction B and denominator of Fraction A (4 x 10), and find the product of both denominators of Fraction A and Fraction B (10 x 5) and rewrite the equation as like the below:
    = (7 x 5) - (4 x 10)/(10 x 5)

    step 3 Simplify and rewrite the fraction:
    = (35 - 40)/50
    = -5/50
    = -1/10
    7/10-4/5 = -1/10
    Hence,
    7/10 minus 4/5 = -1/10
