Explanation:

Step1: Count total grid squares

The grid is 10 columns × 10 rows, so total squares: $10 \times 10 = 100$

Step2: Count shaded grid squares

Count the shaded cells: 49

Step3: Calculate shaded percentage

Percent shaded = $\frac{\text{Shaded Squares}}{\text{Total Squares}} \times 100\%$
$\frac{49}{100} \times 100\% = 49\%$

To mentally find 50% of a number, recognize that 50% is equivalent to one-half. Divide the original number by 2, or multiply it by $\frac{1}{2}$ (0.5). This works because 50% represents half of the total value of the number.

Answer:

49%
