To find the percent represented by the shaded portion on a 10 × 10 grid (which has a total of 100 squares), we can use the following formula:
\[ \text{Percent} = \left( \frac{\text{Number of shaded squares}}{\text{Total number of squares}} \right) \times 100 \]
Given that there are 76 shaded squares:
\[ \text{Percent} = \left( \frac{76}{100} \right) \times 100 \]
Simplifying this gives:
\[ \text{Percent} = 76 % \]
Neither of the provided options of \(7.5%\) or \(75%\) is correct. However, if we choose the closest percentage based on common errors in rounding or representation, \(75%\) would be the closest real-world approximate answer.
So, the final answer is:
75%.
