In this lesson I will teach you the basic of ratios, rates and proportions. Rates and ratios are nothing more than fractions and proportions are two equal fractions. Before you get into this lesson make sure you have a solid understanding of fractions and solving equations. Like I was saying rates and ratios are fractions but the key thing we will be focusing on is rates and ratios are fractions that have units of measure involved. For example, I can have the fraction 1/3 – no big deal. But if I take that same fraction and write it as 1 teacher / 3 students I now would have a ratio- see the difference? Also ratio and rate problems are very common on tests like the SAT, ACT and even the GED- so make sure you practice everything I go over in the lesson.
