Students learn to recognize and represent proportional relationships in tables and by graphing ordered pairs on the coordinate plane, and to determine the constant of proportionality.A proportion is an equation comparing two ratios. If the ratios are equivalent, the proportion is true. If not, the proportion is false. Finding a cross product is another method for determining whether a proportion is true or false. Cross multiplying is also helpful for finding an unknown quantity in a proportional relationship.
