We know that fraction is a part of a whole. It is not complete in itself & has two parts, a numerator & a denominator. Fractions, when taken more than one at a time, may be classified as like & unlike fractions. Whereas like fractions have the same denominator, the unlike fractions have different denominators.

With fractions also, we can carry out any of the mathematical operations of addition, subtraction, multiplication & division. Let us see how the adding unlike fractions calculator works.

When we have to add any number of unlike fractions, we first need to find the LCM of their denominators. Next, we find their equivalent fractions with the LCM as the denominator if each of the fractions given as addendents . To get the final sum, we add the numerators of the equivalent fractions so arrived at. This sum as the numerator & LCM as the denominator is the resulting fraction which is the sum of the given unlike fractions. This sum, if possible should be reduced to its lowest form to get the final answer.

Example: Suppose we are given three fractions to find the sum & the fractions are: 2/3 , 5/6 , 3/2. On observation, we find that these fractions to be added are unlike fractions. So to add them, we will first find the LCM of their denominators. The denominators are 2 ,3, 6 . We know that the LCM of 2, 3, 6 is 6.

Now, we will change all the three fractions to their equivalent fractions with each fraction having the denominator 6 . Thus, the three fractions to be added will now be :

2/3= (2*2)/(3*2)=4/6

5/6=5/6

3/2=(3*3)/(2*3)=9/6

Hence, 2/3 + 5/6 + 3/2= 4/6 + 5/6 + 9/6= (4+5+9)/6= 18/6=3
