Finding One Fifth of 15

This example demonstrates how to calculate one fifth of 15 using GeoGebra by constructing geometric shapes. Key math concepts include fraction computation, geometric construction, and sequence generation. GeoGebra commands used are Circle and Sequence, creating points O, c, and a sequence of points A1 through A15. Suitable for middle school students and above to learn fractions, geometric constructions, and sequences, as well as for mathematical teaching demonstrations.
