Question

1. shade 80% of the grid.

Explanation:

Step1: Determine total cells

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

Step2: Calculate shaded cells

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

Answer:

Shade 80 cells in the 10x10 grid (e.g., 8 full rows or equivalent combination).
