The general idea in these problems is that we have two quantities that both change at the same rate. For example, in the top problem we have (1) gasoline, measured in gallons, and (2) money, measured in dollars. We know both quantities (both the dollars & gallons) for one situation (2 gallons costs $5.40), we know ONE quantity for the other situation (either the dollars or the gallons), and are asked the missing quantity (in this case, the cost for 5 gallons)., Represent proportional relationships by equations. For example, if total cost t is proportional to the number n of items purchased at a constant price p, the relationship between the total cost and the number of items can be expressed as t = pn., How to teach proportions To introduce proportions to students, give them tables of equivalent rates to fill in, such as the one below.
