This video is from Sal Khan about converting decimals using the problem: Write 2.75 as a simplified fraction.
Mr. Khan uses computer software for demonstration. The screen is a little 'busy' so the viewer may want to open the screen to 'full screen...' to see all more clearly. (02:42)[more]

Instructor uses a white board to demonstrate how to convert percents to fractions. Examples include percents both less than and greater than than 100%. The instructor uses the method of taking the percent and making it the numerator of a fraction w...hose denominator is 100 and then reducing the fraction to simplest form.[more]

The instructor uses PowerPoint to explain how to convert between fractions, decimals and percents. Definitions are given and examples model converting between the FDP as well as finding a fractional part of a whole. A calculator is used for computa...tion.(09:39)[more]

Instructor uses a white board to demonstrate how to convert between decimals and percents. The method used is moving the decimal point two spaces to the right to convert a decimal to a percent and moving the decimal point two spaces to the left to c...onvert a percent to a decimal.[more]

In this video they discuss what a percent is and how to apply it to a problem. They show a visual representation of how to change a percent into a percent. They also show how to put a percent into decimal form. The rule they explain is "to change a d...ecimal to a percent, move the decimal right two times since we are multiplying by 100." A few examples are shown. Then they move to writing a quantity as a percent. A few examples of this are shown. Video is good quality and good for all students as a review or initial learning of the topic.[more]
