Equations of Graphs of Proportional Relationships Involving Fractions

The 15th segment in a series of 22 uses examples that present proportional relationships with fractions. Pupils work through the problems and discover the process is the same as it is with whole number values. Graphing the proportional relationship allows the class to view the values that are easier to use in calculations.
