This example demonstrates the process of dividing fractions. It involves the core mathematical concept of fraction division. Using GeoGebra commands such as Intersect, Point, Polygon, etc., a geometric model of fraction division is constructed. Suitable for high-grade elementary or junior high school students to learn the concept and operations of fraction division.

GeoGebra Commands & Parameters

  1. Intersect(xAxis, yAxis) → U
  2. Point(xAxis) → R
  3. Point(yAxis) → T
  4. Polygon(U, R, S, T) → poly1, q, r, s, t
  5. Polygon(T, X1, X2, U) → poly2, t_1, f1, f2, q_1
  6. Segment(B2, B1) → f
  7. Segment(C2, C1) → g
  8. Segment(D2, D1) → h
  9. Segment(E2, E1) → i
  10. Segment(F2, F1) → j
  11. Segment(G2, G1) → k
  12. Segment(H2, H1) → l
  13. Segment(I2, I1) → m
  14. Segment(A2_1, A1_1) → n
  15. Segment(B1_1, B2_1) → p
  16. Segment(C2_1, C1_1) → a_1
  17. Segment(D2_1, D1_1) → b_1
  18. Segment(E2_1, E1_1) → c_1
  19. Segment(F2_1, F1_1) → d_1
  20. Segment(G2_1, G1_1) → e_1
  21. Segment(H2_1, H1_1) → f_1
