This activity asks students to use proportions to find a missing unit cost or unit weight for various amounts of fruit. This should be used as practice after students have a solid understanding of how to use a proportion to find a missing value.

This is a task from the Illustrative Mathematics website that is one part of a complete illustration of the standard to which it is aligned. Each task has at least one solution and some commentary that addresses important aspects of the task and its potential use. The Virginia Department of Education Resource titled, "Telling the Tale," walks students through a real world exercise analyzing a linear relationship.

Students will complete this assignment by stating if each pair of ratios forms a proportion.  Students solve by cross multiplying.  Students will write answers on a sticky note.
