Question

which model shows 70%?

Explanation:

Step1: Count total parts of each model

Top model: 4 parts; Middle model: 10 parts; Bottom model: 10 parts.

Step2: Calculate percentage of colored parts

Top: $\frac{3}{4}=75\%$; Middle: $\frac{7}{10}=70\%$; Bottom: $\frac{7}{10}=70\%$? Wait, check again: Middle has 7 red out of 10, bottom has 7 yellow out of 10? Wait no—wait the middle model: 7 red and 3 white? Wait no, original image: middle is 6 red? Wait no, let's recheck: The middle model (red) has 6 colored? No, wait the correct one is middle: 7 colored? Wait no, 70% is 7/10. So the model with 7 colored parts out of 10. The middle model (red) has 6? No, wait the user's image: middle is 6 red? Wait no, the correct answer is the middle one? Wait no, let's see: Top: 3/4=75%, Middle: 6/10=60%? No, wait maybe I miscounted. Wait the bottom model: 7 yellow out of 10? Yes, 7/10=70%. So bottom model.

Wait correction: Bottom model has 7 yellow and 3 white (total 10 parts), so 7/10=70%.

Answer:

The bottom model (yellow)
