Step-by-step explanation:

The steps in the question isn't clear enough, however the question is answerable.

From the question, we understand that one model shows that:

200 is 10 times 20

While the second model shows that

200 is 10 times 2

The first model that says

200 = 10 times 20 makes sense.

This is so, because 200 = 20 * 100

While the other model which says

200 = 10 * 2 is nonsense.

This is so because, 200 ≠ 10 * 2
