To find the percentage of shaded squares in a grid model with 100 squares, you can use the formula:
\[
\text{Percentage} = \left(\frac{\text{Number of shaded squares}}{\text{Total number of squares}}\right) \times 100
\]
In this case, the number of shaded squares is 9 and the total number of squares is 100.
So,
\[
\text{Percentage} = \left(\frac{9}{100}\right) \times 100 = 9\%
\]
Therefore, the correct answer is **9%**.
\[
\text{Percentage} = \left(\frac{\text{Number of shaded squares}}{\text{Total number of squares}}\right) \times 100
\]
In this case, the number of shaded squares is 9 and the total number of squares is 100.
So,
\[
\text{Percentage} = \left(\frac{9}{100}\right) \times 100 = 9\%
\]
Therefore, the correct answer is **9%**.
