Solving Proportions Using Cross Products

Today, we looked at fractions again, and remembered how to write equivalent forms of the fraction. When we came up with a pair of equivalent fractions, we noted that the cross products of the fractions were also equivalent. Using this notion, we started solving more complex equations. Students must show all steps of the process (write down the problem, show the cross products, simplify, and then solve) in order to get full credit on tonight's homework.
