Add & Subtract Rational Fractions Worksheets

How to Find the Sum and Difference of Rational Fractions - Rational fractions are those fractions whose denominators are always larger than their numerators. Finding sums and differences of such fractions is the same as finding sums and differences of their irrational counterparts. All you have to do is find the L.C.M. of both the denominators of those terms that you are going to add, divide that L.C.M. with the denominators of both terms, and multiply their results with their respective numerators. This is the standard method of finding the sums and differences of any types of fractions. While adding or subtracting rational fractions, one thing that is pretty much observable is that the answer we get while taking the L.C.M. of the denominators is usually a very large number, so dividing that by both the denominators and multiplying the answers with their respective numerators can be a bit of a hassle. So, this is all about finding the sum and difference of rational fractions.
