In this online analytical calculator, you can add multiple fractions with different denominators. 'Unlike fractions' are fractions with different denominators. To add unlike fractions, it is necessary to find the LCM of the denominators and which is kept as the denominator of the resultant fraction. In the below Adding Unlike Fractions Calculator enter the number of fractions to be added and values for each fraction with different denominators and click calculate.

Code to add this calci to your website  Formula:

lcm = LCM (b1, b2, b3, ...) Sum of Unlike denominators = (a1*(lcm/b1) + a2*(lcm/b2) + a3*(lcm/b3) + ...) / lcm Where, a1, a2, a3 = Numerators b1, b2, b3 = Denominators LCM = Least Common Multiple

Example:

Add Multiple Fractions with Different Denominators for the values a1 as 5, a2 as 7, b1 as 4 and b2 as 8.

Solution:

lcm = LCM (b1, b2, b3, ...)
Sum of Unlike denominators = (a1*(lcm/b1) + a2*(lcm/b2) + a3*(lcm/b3) + ...) / lcm
= 17 / 8
= 2.125
