This example demonstrates multiplying fractions. The core mathematical concepts involved are fraction multiplication. Using GeoGebra commands such as Random, GCD, Div, Mod, a series of random fraction multiplication problems are constructed. Suitable for high-grade elementary or junior high school students to practice fraction multiplication.
