# 3 Part Ratios

Students learn how to use proportional reasoning to solve problems involving 3-part ratios.  As learning progresses they use equivalence and the unitary method to compare shares.
##### Differentiated Learning Objectives
• All students should be able to simplify a 3-part ratio using the highest common factor.
• Most students should be able to combine two 2-part ratios into a 3-part ratio.
• Some students should be able to share amounts between a 3-part ratio
