This example demonstrates how to solve ratio problems using tables and calculations. Core math concepts include direct and indirect proportions, table application, calculation, and verification. It uses commands like Semicircle, SelectedIndex, Textfield, If, Polygon, Point from GeoGebra. Suitable for 5-6 grade students learning ratio calculations and real-world applications.
