Students will need to use the recipe at the bottom, which is written for more than one serving, and convert it to find the serving for one person. You can extend this activity by having students graph the unit rates on a coordinate plane to show that unit rates can also be used as the slope of a linear function.
8.EE.5 Graph proportional relationships, interpreting the unit rate as the slope of the graph. Compare two different proportional relationships represented in different ways. Graph proportional relationships.
