20. Represent $\frac{2}{15} \times \frac{5}{8}$ using each of the following models. Be sure the pictures are well labeled. It should clear how the model tells you the answer. A. area model (the bounding rectangle needs to have whole number White side lengths and regions should be divided up in such a way) B. Cuisenaire rods: You can reference the rods by referring to their colors instead of their lengths (e.g., \"the brown rod\" instead of \"the 8 rod\"). You must specify which rod(s) represents 1. C. number line both as $\frac{2}{15}$ of $\frac{5}{8}$ and as $\frac{5}{8}$ of $\frac{2}{15}$. 1 Red 2 Light green 3 Purple 4 Yellow 5 Dark green 6 Black 7 Brown 8 Blue 9 Orange 10

Step 1
Area model: To represent 20 using an area model, we need to find a rectangle with whole number side lengths that can be divided into easily distinguishable regions. One possible way to represent 20 is by using a rectangle with dimensions 4 by 5. We can divide this Show more…

(b) Find the area of the shaded region below. The grid lines are spaced one unit apart. You may use any area formulas that we have learned in class for this part. To receive credit, your work must clearly indicate what you have done to find the area. This may include modifying the picture, labeling parts of it, and giving a written explanation of what you did.
