Given that the area model has 4 shaded parts (representing two-thirds) and 2 unshaded parts, it is set up to illustrate the relationship between the parts and the whole.
Since the shaded part represents two-thirds, the model specifically helps to solve questions related to how many parts of one kind fit into another. In this case, the model would be most helpful in addressing the question:
How many One-sixths are in Two-thirds?
This is because the model represents the two-thirds visually, allowing Layla to easily see how many one-sixths can be found within that portion. The other questions either involve larger wholes or ratios that are not represented in the area model as clearly.
