Where do you see the expression of the diagram?

• There are 2/4 X 9 rows of shaded area.

• 2 X 9 =18. 18 X 4= 72/4

• The squares are each divided in fourths. Each row has 9 shaded fourths. There are two rows of these shaded fourths.

• This is incorrect. There are 2 rows, but there are 9/3 shaded.
