In collections Module 2: Fractions
This example demonstrates the calculation process of dividing fractions. It involves core mathematical concepts such as fraction operations, greatest common divisor (GCD), division, modulus, and conditional statements. GeoGebra commands and objects like Random, GCD, Div, Mod, If are used in the construction. It is suitable for middle school mathematics teaching, helping students understand the principles and methods of fraction division.
