Description:

This Java applet displays the multiplication of two fractions as an overlaying of rectangular areas. The left rectangle illustrates the left fraction as a horizontal fraction bar; the right rectangle shows the right fraction as a vertical fraction bar; and the middle rectangle represents their overlay. To change the numerator or denominator of the multiplicands, click a digit slightly off-center (left to decrease, right to increase).
