Lesson 8: Adding and Subtracting Fractions with... (4:25)
A CHAPTER FROM: Math Mastery: Fractions
Students find the first common number, or lowest common denominator, when adding or subtracting fractions with unlike denominators. They then convert the fractions in each problem so that they have common denominators in order to find the solution.
