Modeling With Multiplication of Fractions

Draw a visual representation of multiplying 2/3 by 1/4 using a rectangular area model.

• Drawing a circle and shading 2/3 of it and then shading 1/4 of it

• Using a pie chart to represent the multiplication of 2/3 and 1/4

• Drawing a line graph to show the multiplication of 2/3 and 1/4

• A visual representation of multiplying 2/3 by 1/4 using a rectangular area model can be drawn by dividing a rectangle into 3 equal parts horizontally and 4 equal parts vertically, then shading 2 of the 3 horizontal parts and 1 of the 4 vertical parts to represent the product.
