For high school students. Solving a Mixture problem with algebra. Seasoned math instructor demonstrates on white board. Uses colored markers for clarification.

The instructor in this video, Sal Khan, continues to discuss solving mixture problems. This problem involves percentages and how to use a table to help solve the problem. Mr. Khan uses the Paint Program (with different colors) to illustrate his point...s. Sal Khan is the recipient of the 2009 Microsoft Tech Award in Education. The student or educator may want to open the video to 'full screen' as the instructor is using a black background and the writing is small.[more]

This is an excellent clip from a larger segment. The instructor continues to solve this problem: How many grams of pure silver does a silversmith need to mix with s 45 percent silver alloy to produce 200 grams of a 50 percent silver alloy? (05:12)

Using information to write an equation and solve a word problem, the instructor uses whiteboard to demonstrate. Students learn to solve "mixture" word problems -- for example, adding two acid solutions together, or adding water to a sugar solution. S...tudents then set up a chart based on the mixture formula, which states that the amount of solution times the percent of acid = amount of acid (or the amount of solution times the percent of sugar = amount of sugar). The chart is then used to set up the equation. Suitable for high school students.[more]

Writing an equation and finding the amounts of two different antifreeze solutions that must be mixed to obtain the desired antifreeze solution. Suitable for high school students. Instructor uses white board and markers.
