which model is 85% shaded?

Explanation:

Step1: Assume each model has 20 small - squares.

Since we need to find 85% of 20.

Step2: Calculate 85% of 20.

$85%=\frac{85}{100}=0.85$, and $0.85\times20 = 17$. We need to find the model with 17 shaded squares.

• In the first model: Count the shaded squares, there are 17 shaded squares.
• In the second model: There are 14 shaded squares.
• In the third model: There are 16 shaded squares.
• In the fourth model: There are 15 shaded squares.

Answer:

The first model.
