## Percents as Ratios## In this first video we'll take a look at how to solve basic percent problems using ratios and cross multiplication. I don't recommend using this method for long, though, since I've seen so many students struggling with this percents stuff years later while preparing for the SAT, who still set up equations with x/100. Use it to learn percents, but try and move on to the decimal methods in the later videos as soon as possible! |
