 Amsco Integrated Algebra I: Adding or Subtracting Algebraic Fractions
This is a free lesson from our course in Amsco's Integrated Algebra
 
   
This lesson covers the concepts on how to add and subtract algebric fractions having same or different denominators. The approach is simple and common rule for adding or subtracting fractions is: The denominators must be the same, then add or subtract the numerators, and place their sum/difference over the common denominator. E.g. x/y +z/y = x +z/y or x/y - z/y = x - z/y.
Further you'll learn the concepts and steps to add or subtract having same or different denominators:
•write a fraction whoes numerator is the sum(or difference) of the numerators and whose denominator is the common denominator of the given fractions.
• reduce the resulting fraction in lowest terms.
• for example, 5/4x+9/4x=(5+9)/4x=14/4x=7/2x. (More text below video...)

(Continued from above) To add or subtract fractions having different denominators steps are:
• find a common denominator for these fractions.
•change each fraction to an equivalent fraction with the chosen common denominator.
•write a fraction whoes numerator is the sum(or difference) of the numerators of the new fractions and whose denominator is the common denominator.
•reduce the resulting fraction in lowest terms.
For example, 5/a2b+ 2/ab2=(5/a2b)(b/b)+(2/ab2)(a/a)=5b/a2b2+2a/a2b2=(5b+2a)/a2b2.

 
   

As many of you know, Winpossible's online courses use a unique teaching method where an instructor explains the concepts in any given area to you in his/her own voice and handwriting, just like you see your teacher explain things to you on a blackboard in your classroom. This particular lesson includes the teacher's instruction, practice questions as well as end-of-lesson quizzes for practice. As we mentioned above, you can enroll in our online course in Trigonometry by clicking here.

The format of Winpossible's online courses is also very suitable for teachers who are using an interactive whiteboard such as Smartboard on Promethean in their classrooms, because the course lessons can be easily displayed on such interactive whiteboards. Volume pricing is available for schools interested in our online courses. For more information, please contact us at educators@winpossible.com.
