    How to Find the Sum of Multiple Fractions

    For fractions which are having same or equal denominators, the sum of fractions is equals to the sum of numerators divided by the common denominators, while for fractions with unlike, unequal or different denominators, the sum of fractions is calculated by using the LCM (least common multiple) method. Users may refer the below solved examples with step by step calculation to learn how to find the equivalent fraction by adding two, three or more fraction numbers with same or unlike denominators.

    Adding Three Fractions with Unlike Denominators

    The below solved example with step by step calculation or workout may help users to know how to find the equivalent fraction by adding three fractions (with unlike or different denominators) 1/2, 2/3 & 4/5.
    Problem
    Find the sum of three fractions with unlike or different denominators such as 1/2, 2/3 & 4/5.

    Step by step workout
    step 1 Address formula, input parameters & values.
    Input parameters & values:
    1/2,2/3,4/5
    1/2+2/3+4/5= ?

    step 2 For fractions with different denominators, find the LCM (least common multiple) for all denominators. 30 is the LCM for 2, 3 and 5.

    step 3 Multiply LCM 30 with each numerators & denominators
    =(1 x 30)/(2 x 30)+(2 x 30)/(3 x 30)+(4 x 30)/(5 x 30)

    step 4 Simply the above expression to have same denominators for all fractions.
    =15/30+20/30+24/30
    =(15 + 20 + 24)/30

    step 5 Add all numerators and rewrite it in a single form.
    =59/30
    1/2+2/3+4/5=59/30

    Thus, 59/30 is the equivalent fraction by adding three fractions 1/2, 2/3 & 4/5.

    Adding Three Fractions with Same Denominators

    1/2, 1,5/3, 2 ,1/4,2/5 , 3
    1/2 + 1 +5/3 + 2 + 1/4 + 2/5 + 3 = ?

    step 2 Convert whole numbers to fractions and rewrite as below
    Any whole number or integer is a rational number (quotient of 1), hence the denominators for all whole numbers is 1 and can be written as
    1 = 1/1
    2 = 2/1
    3 = 3/1

    step 3 Arrange all the numbers as fractions.
    1/2+1/1 + 5/3 + 2/1+ 1/4+2/5+3/1

    step 4 Find LCM (least common multiple) for all denominators, if all the denominators are not identical to each other.
    60 is the LCM for denominators 2, 1, 3, 1, 4, 5 & 1.

    step 5 Multiply LCM 60 with all the numerators & denominators of each fractions
    (1 x 60)/(2 x 60) +(1 x 60)/(1 x 60) + (5 x 60)/(3 x 60)+(2 x 60)/(1 x 60)+(1 x 60)/(4 x 60)+(2 x 60)/(5 x 60) +(3 x 60)/(1 x 60)

    step 6 Simplify and rewrite the above expression to have the common denominators
    30/60+60/60+100/60+ 120/60+25/60+24/60+180/60

    step 7 Add all the numerators and simplify
    =(30 + 60 + 100 + 120 + 25 + 24 + 180)/60
    =539/60
    1/2+ 1 +5/3 + 2 + 1/4 + 2/5 + 3 =539/60

    Thus, 539/60 is the equivalent fraction for adding multiple fractions and whole numbers such as 1/2, 1, 5/3, 2, 1/4, 2/5 & 3.

    5/6,1/3,-2/7,1/6,-4/7,4/5
    5/6+1/3+-2/7+1/6+-4/7+4/5= ?

    step 2 Find the LCM (least common multiple) for all denominators, if all the denominators are not identical to each other.
    210 is the LCM for denominators 6, 3, 7, 6, 7, & 5.

    (5 x 210)/(6 x 210)+(1 x 210)/(3 x 210)+-(2 x 210)/(7 x 210)+(1 x 210)/(6 x 210)+-(4 x 210)/(4 x 210)+(4 x 210)/(5 x 210)

    step 4 Simplify and rewrite above expression to have the common denominators
    175/210+70/210-60/210+35/210-210/210+24/210+168/210

    step 5 Add all the numerators and simplify
    =(175 + 70 - 60 + 35 - 210 + 24 + 168)/210
    =202/210
    =101/105
    5/6+1/3+-2/7+1/6+-4/7+4/5=202/210

    Thus, 202/210 is the equivalent fraction for adding multiple positive & negative fractions 5/6 + 1/3 + (-2/7) + 1/6 + (-4/7) + 4/5.

    Input parameters & values:
    1/2,1/3,1/4, 6 ,71/5, 8 1/6,1/7
    1/2+1/3+1/4 + 6 + 71/5+ 8 1/6 +1/7 = ?

    step 2 Convert whole numbers to fractions and rewrite as below
    6 = 6/1

    step 3 Convert mixed fractions to fractions and rewrite as below
    7 1/5= ((7 x 5) + 1)/5= 36/5
    8 1/6= ((8 x 6) + 1)/6= 49/6

    step 4 Arrange all the numbers as fractions.
    1/2+1/3 + 1/4 + 6/1+ 36/5+49/6+1/7

    step 5 For fractions with different denominators, find the LCM (least common multiple) for all denominators. 420 is the LCM for 2, 3, 4, 1, 5, 6 and 7.

    =210/420 +140/420+105/420+2520/420+3024/420+3430/420+60/420

    step 5 Add all the numerators and simplify
    =(210 + 140 + 105 + 2520 + 3024 + 3430 + 60)/420
    =9489/420
    =3163/140
    1/2+1/3+1/4 + 6 + 71/5+ 8 1/6 +1/7 = 3163/140

    Thus, 3163/140 is the equivalent fraction for adding multiple fractions, mixed & whole numbers 1/2 + 1/3 + 1/4 + 6 + 7(1/5) + 8(1/6) + 1/7.
