Khan Academy: Adding Fractions With Unlike Denominators

If the fractions don't have a common denominator, make them have one. Learners first read and analyze a conversation of pupils trying to add 2/5 and 1/2. They compare the process of adding fractions to the process of adding quantities...

Could you develop your own way to add fractions with unlike denominators? An in-depth task has scholars examine a fictional conversation between several people in which they discuss a method of adding fractions with unlike denominators....

In this math PowerPoint, the process of adding fractions with unlike denominators is broken down into a logical, easy-to-follow sequence of steps. Definitions and examples of multiples, least common multiple, and least common denominator...

Your young mathematicians can solve this problem along with Sal. They will add 4/9 and 11/12 by finding a number that goes into 9 and 12 evenly. Sal fully explains the process of finding a common denominator in a very clear and...

Bring interest to your lesson on adding fractions with different signs by using this Khan Academy video. Sal employs a number line to clearly explain how he adds multiple fractions with different signs. This resource could be used as an...

Assist your students in understanding how to add fractions with like denominators by showing them this presentation. Sal adds 3/15 to 7/15 and then simplifies his answer. He uses drawings and multiple colors to show the actual process.

Adding fractions with unlike denominators is a difficult process to master. This fine presentation does a terrific job of leading young math whizzes through the steps necessary to perform this calculation. The slides have clear graphics,...

In this math worksheet, students subtract and add fractions with unlike denominators. Students solve the problem in steps. They are given examples of how to solve the problems.

A video exploring how to find the common denominator so students can subtract fractions. Video walks you through an example of how to subtract fractions with unlike denominators. [5:00]

Practice subtracting fractions that have different denominators. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.
