This lesson helps to build fluency with equivalent ratios. Ratio tables are used here because it supports students' development of multiplicative relationships in equivalent ratios. This work develops students' understanding that a ratio is a comparison by division.

Students engage in Mathematical Practice 4 (model with mathematics) as they apply ratio reasoning to a real life situation.

**Key vocabulary:**
