Question

1. shade 80% of the grid

Explanation:

Step1: Determine total grid cells

Assume the grid is a 10x10 grid (common for such problems), so total cells = \(10\times10 = 100\).

Step2: Calculate 80% of total cells

80% of 100 is \(0.8\times100 = 80\) cells.

Step3: Shade 80 cells

Shade 80 out of the 100 cells in the grid (e.g., shade 8 rows of 10 cells each, or any combination that totals 80).

Answer:

Shade 80 out of the 100 cells in the 10×10 grid (e.g., 8 full rows or an equivalent combination).
