Comparing Ratios
... When comparing ratios, students should be able to use more than one strategy for drawing conclusions. What to look for As students explore the activity, they should compare two ratios by looking at tables of equivalent ratios for each given ratio. They will also compare the ratios by ident...https://education.ti.com/en/building-concepts/activities/ratios/sequence1/comparing-ratios
