This video explains how to add fractions with different denominators. Several examples are used to help reinforce the concept. The instructor, in his conversational tone, uses a black screen as a 'chalkboard.' Different colors and pictures are used ...for clarification. (04:05)[more]

In this video they show how to add fractions with unlike denominators. The LCD or lowest common denominator is found and the fractions are converted. The LCD method is shown to students. Then the fractions are added. At the end of the video there are... problems for the students to practice on. Video is good quality and good for all students as a review or initial learning of the topic. (04:05)[more]

John, a math teacher, uses a small whiteboard in this short two-minute tutorial to demonstrate how to add fractions with different denominators. The video goes step-by-step and is easy to understand.(02:07)

How do you add tenths and hundredths? For example, how would you add 7/10 and 9/100? In this video lesson, learn how to add tenths and hundredths by creating equivalent fractions. (4:46)

This method will produce the correct answer every time, but the student may have to simplify the fraction once finished. Nonetheless, at least the student can produce the correct answer every time! (04:59) Note: Any mixed numbers have to be changed t...o improper fractions first.
1) Multiply the denominators (bottom numbers). This is the denominator in your answer.
2) Multiply the diagonals. Place the answers above the fractions (see video).
3) Add the numbers you placed above the fractions (this is the numerator of your answer [top number]). Another Note: You can use this method for subtraction of fractions. To do that, change "add" to "subtract" in step 3.[more]

This video takes a simple fraction and the steps to go through to find the answer. Practices finding the common denominator and the LCD (least common denominator). Gives visual examples of the problem being solved using what the instructor calls a fr...action bar. This example is very clear and students can easily substitute the numbers if used for homework help.[more]
