Then, we shade of . We can see that it is the same as . To find the answer to , we will use the model to find of . Then, we shade of . We can see that it is the same as . In this example, of has been shaded PPT Slide In the second method, we will think of multiplying fractions as multiplying a length times a length to get an area. In the second method, we will think of multiplying fractions as multiplying a length times a length to get an area. We think of the rectangle having those sides. Its area is the product of those sides. We can find another name for that area by seeing what part of the square is shaded. We have two names for the same area. They must be equal. Length X Length = Area What is the answer to X ? PPT Slide In the third method, we will represent both fractions on the same square. The product of the two fractions is the part of the square that is shaded both directions. We will look at another example using cross shading. We shade one direction.
