Adding Multiple Fractions Calculator

Here is the online adding multiple fractions calculator for unlike and like denominators. Fraction involves simple process of adding the numerator when the denominators remains same. For unlike fractions, it takes a few step process. We need to take LCM to convert the unlike to like denominators. Using this online calculator saves lot of time and performs calculations of adding Multiple Fractions with Like/Unlike Denominators at a few fraction of second.

Formula:

lcm = LCM (b1, b2, b3, ...) Sum of Fractions = (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 Like Denominators for the values a1 as 5, a2 as 4, b1 & b2 as 7.

Solution:

lcm = LCM (b1, b2, b3, ...)
Sum of Fractions = (a1*(lcm/b1) + a2*(lcm/b2) + a3*(lcm/b3) + ...) / lcm
= 9/7
= 1.2857
