Interactive GeoGebra activity: multiplying fractions ≤ 1

- Consider \(\frac{4}{4} \times \frac{1}{3}\). This is equivalent to \(1 \times \frac{1}{3}\) so we would expect the product to be \(\frac{1}{3}\), as shown in the applet’s initial configuration.
- Tick the box to show the vertical splits.
- Start reducing the numerator of the first fraction while holding everything else constant for a visualisation of \(\frac{3}{4} \times \frac{1}{3}, \frac{2}{4} \times \frac{1}{3},\) and \( \frac{1}{4} \times \frac{1}{3}\).
- Continue to play around with this applet!
