SequenceGeometric Construction
This example demonstrates the concept of equivalent fractions. It involves core mathematical concepts such as fraction simplification and conversion. Using the GCD (Greatest Common Divisor) command, users can generate equivalent fractions. This example is suitable for high-grade elementary and junior high school students to learn basic fraction concepts.

GeoGebra Commands & Parameters
