Final answer:
To find out how many parts would be shaded when evenly dividing the answer 12 with a model, we consider the available options. This leads us to conclude that the correct answer is 6.
Step-by-step explanation:
To evenly divide the answer with a model, you would divide each circle into equal parts. To find out how many parts would be shaded, let's look at the question. The question asks about dividing the number 12 into equal parts with a model. So, let's consider the options given (A, B, C, D).
Option A: If we divide 12 into 3 equal parts, each part would be shaded.
Option B: If we divide 12 into 4 equal parts, each part would be shaded.
Option C: If we divide 12 into 6 equal parts, each part would be shaded.
Option D: If we divide 12 into 8 equal parts, each part would be shaded.
From these options, it seems that the correct answer is option C, which is 6.
