Understanding Ratios and Proportions

Penelope and her beetle friend Harold explore proportional relationships in math. They demonstrate how to create and expand a table for dye ratios, use Harold's speed data to understand proportions and graphs, and introduce a project on curing math phobia. The video covers key concepts like ratios, proportions, and graph interpretation.
