For a complete lesson on mixture problems, go to http://www.MathHelp.com – 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students learn to solve “mixture” word problems — for example, adding two acid solutions together, or adding water to a sugar solution. Students 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.
