Question

which grid has $\frac{1}{2}$ shaded?

Explanation:

Step1: Count total and shaded cells (Top-left grid)

Total cells: $3 \times 6 = 18$; Shaded cells: $9$. Ratio: $\frac{9}{18} = \frac{1}{2}$

Step2: Check other grids (Top-right)

Total cells: $3 \times 6 = 18$; Shaded cells: $6$. Ratio: $\frac{6}{18} = \frac{1}{3}$

Step3: Check other grids (Bottom-left)

Total cells: $3 \times 6 = 18$; Shaded cells: $12$. Ratio: $\frac{12}{18} = \frac{2}{3}$

Step4: Check other grids (Bottom-right)

Total cells: $3 \times 6 = 18$; Shaded cells: $9$. Ratio: $\frac{9}{18} = \frac{1}{2}$

Answer:

The Top-left Grid and The Bottom-right Grid
