    What is 3/4 plus 1/7 as a fraction?

    step 1 Observe the input parameters and what to be found:
    Input:
    Fraction A: 3/4
    Fraction B: 1/7

    What to be found?
    3/4+1/7 = ?
    Find what's the sum of 3/4 and 1/7.


    step 2 Compare the denominators of fractions 3/4 and 1/7 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 3/4 and 1/7 are not equal, it is said to be unlike fractions addition.

    step 3For unlike fractions addition, find the LCM (least common multiple) of both denominators of fractions 3/4 and 1/7:
    The LCM of 4 and 7 is 28.


    step 4 Write the fractions 3/4 and 1/7 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
    =3/4+1/7
    =(3 x 28)/(4 x 28)+(1 x 28)/(7 x 28)


    step 5 Simplify the expression to have common denominator:
    =21/28+4/28


    step 6 Take the common values out and rewrite the above expression like the below:
    =1/28 x (21/1+4/1)
    =1/28 x (21 + 4)


    step 7Simplify the above expression further:
    =1/28 x 25
    =25/28
    3/4+1/7=25/28

    Hence,
    3/4 plus 1/7 equals to 25/28 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: 1/7

    What to be found?
    3/4+1/7 = ?
    Find what's the sum of 3/4 and 1/7.

    step 2 Find the product of numerator of Fraction A and denominator of Fraction B (3 x 7), 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 7) and rewrite the equation as like the below:
    = (3 x 7) + (1 x 4)/(4 x 7)

    step 3 Simplify and rewrite the fraction:
    = (21 + 4)/28
    3/4+1/7 = 25/28
    Hence,
    3/4 plus 1/7 = 25/28
