Workout for Sum of 1 1/2, 1/3, 2 1/3, 3 1/4, 5, 5 2/3 & 6 5/7
Example Problem
Find the sum of 1 1/2, 1/3, 2 1/3, 3 1/4, 5, 5 2/3 and 6 5/7.
Step by step workout
step 1 Input values:
11/2, 1/3, 21/3, 31/4, 5, 52/3, 65/7
Total count = 7
step 2 Convert the mixed numbers to corresponding fractions form, if any.
Fraction form = (whole number x denominator) + numerator/denominator
11/2 = (( 1 x 2 ) + 1)/2=3/2
21/3 = (( 2 x 3 ) + 1)/3=7/3
31/4 = (( 3 x 4 ) + 1)/4=13/4
52/3 = (( 5 x 3 ) + 2)/3=17/3
65/7 = (( 6 x 7 ) + 5)/7=47/7
step 3 Convert the whole numbers to corresponding fractions form, if any.
, 5 = 5/1
step 4 Arrange all the numbers as fractions.
3/2+1/3+7/3+13/4+5/1+17/3+47/7
step 5 Compare all denominators of the fractions, if they are not same, find the LCM (least common multiple) for all denominators. 84 is the LCM for 2 , 3 , 3 , 4 , 1 , 3 , 7 .
step 6 Multiply LCM 84 with each numerators and denominators
= (3 x 84)/(2 x 84)+(1 x 84)/(3 x 84)+(7 x 84)/(3 x 84)+(13 x 84)/(4 x 84)+(5 x 84)/(1 x 84)+(17 x 84)/(3 x 84)+(47 x 84)/(7 x 84)
step 7 Simply the above expression to have same denominators for all fractions.
=(3 x 42)/84+(1 x 28)/84+(7 x 28)/84+(13 x 21)/84+(5 x 84)/84+(17 x 28)/84+(47 x 12)/84
=126/84+28/84+196/84+273/84+420/84+476/84+564/84
=126 + 28 + 196 + 273 + 420 + 476 + 564/84
step 8 Add all numerators and rewrite it in a single form.
=2083/84
Fraction Form:
11/2+1/3+21/3+31/4+5+52/3+65/7= 2083/84
Decimal Form:
11/2+1/3+21/3+31/4+5+52/3+65/7= 24.8
2083/84 is an equivalent fraction for adding fractions with same or different denominators, whole numbers and mixed numbers 1 1/2, 1/3, 2 1/3, 3 1/4, 5, 5 2/3 and 6 5/7.
