To assess the shaded parts of the rectangles in the model you described:
-
First Rectangle: It has two equal parts, with both parts shaded. This means that the shaded part represents the whole, or 1 (since both parts are shaded).
-
Second Rectangle: It also has two equal parts, with one part shaded. This means that the shaded part represents half of the whole, or \( \frac{1}{2} \).
To determine which fraction the shaded part represents, we can analyze:
- The shaded part of the first rectangle is 1 (whole).
- The shaded part of the second rectangle is \(\frac{1}{2}\).
If the question is asking for what fraction represents the shaded part of the entire model comprised from these two rectangles, the total shaded area would combine the contributions from both rectangles.
Thus, we could say the shaded parts of the model collectively represent:
- From the first rectangle: 1
- From the second rectangle: \(\frac{1}{2}\)
So the total shaded portion of the model would be \( 1 + \frac{1}{2} = \frac{3}{2} \).
To summarize, depending on the context or if we are asked to express the shaded part in relation to a singular rectangle or as a compounded fraction, we analyze accordingly. If the specific question is looking for a commonly understood fraction that describes the shaded portion related to the entire model subtly, the answer could also be taken to refer just to the second rectangle indicating a simple representation of \( \frac{1}{2} \).
If the context of the question defines the total area being considered, it may provide a more definitive response.
