This example demonstrates how to simplify fractions using GeoGebra. It involves basic fraction concepts such as numerator and denominator simplification. Using GeoGebra commands like Segment, Ray, Point, etc., the process of fraction simplification is visually demonstrated. Suitable for high-grade elementary and junior high school students to learn basic fraction operations.
