Comparing population proportions 1 | Probability and Statistics | Khan Academy
By Khan Academy
For qualitative variables, the population proportion is a parameter of interest. A point estimate of the population proportion is given by the sample proportion. With knowledge of the sampling distribution of the sample proportion, an interval estimate of a population proportion is obtained in much the same fashion as for a population mean.
Speed translation | Ratios, proportions, units, and rates | Pre-Algebra | Khan Academy
By Khan Academy
This video takes us through some more advanced unit conversion problems. Here, we can see how to make multiple conversions in the same problem concerning speed. Take particular note of how the units change in each step. More importantly, note how, step by step, our units slowly change into the units we want for our final answer. If you are having trouble understanding why this happens, go to the key concept described at 2:20 in the video. Note that this only occurs when multiplying two quantities, not when adding them!
Finding average speed or rate | Ratios, proportions, units, and rates | Pre-Algebra | Khan Academy

How to use Ratios and Proportions to Solve Real World Problems
By mrtedmartin
Instructor uses a Power Point presentation to demonstrate how to use ratios and proportions to solve problems real world problems. Unit rates are discussed and definitions are given. Solving unit rate problems are modeled and a calculator is used for computation.
Solving rational equations 2 | Polynomial and rational functions | Algebra II | Khan Academy
By Khan Academy
The instructor in this video (04:08) discusses how to solve rational equations using another problem. Sl Khan shows how to multiply to remove the fractions to make solving easier. He uses computer software for demonstration. The viewer may want to open the video to 'full screen' because the instructor has a lot of small writing on a black screen.
Solve equations with one rational expression (advanced)
By Khan Academy
Sal solves the following equation by first simplifying the rational expression: x^2-(x^2-4)/(x-2)=4.
Solve equations with two rational expressions
By Khan Academy
Sal solves the following equation and eliminates the resulting extraneous solution: (x^2)/(x+2)=4/(x+2).
