This example demonstrates the process of multiplying fractions. It involves the core mathematical concept of fraction multiplication. Using GeoGebra commands such as Polygon, Sequence, and Segment, a geometric model of fraction multiplication can be constructed. Suitable for high-grade elementary or junior high school students to learn the concept and operations of fraction multiplication.

GeoGebra Commands & Parameters

  1. Polygon((0, 0), (c / d, 0), (c / d, a / b), (0, a / b)) → pol, e, f, g, h
  2. Sequence(Polygon[(Mod[i, 3], Div[i, 3]), (Mod[i, 3] + 1, Div[i, 3]), 4], i, 0, 8) → squares
  3. Sequence(Segment[(i / d, 0), (i / d, 3)], i, 0, (d * 3)) → verSeg
  4. Sequence(Segment[(0, i / b), (3, i / b)], i, 0, (3 * b)) → horSeg
  5. Segment((0, 0), (c / d, 0)) → bSeg
  6. Segment((0, 0), (0, a / b)) → hSeg

AI Drawing Prompt Reference

Draw a geometric model of fraction multiplication, including a rectangle representing the product of fractions a/b and c/d, divided into smaller squares, with vertical and horizontal grid lines dividing the rectangle into corresponding cells, illustrating the process of fraction multiplication.
