to start, shade 40% of the grid. click and drag to shade. write 40% as a decimal. 40% = 0.40 write 40% as a fraction in simplest form. 40% =

Explanation:

Step1: Calculate total grid cells

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

Step2: Find 40% of grid cells

Calculate number of cells to shade: $40\% \times 100 = 40$

Step3: Convert % to decimal

Divide percentage by 100: $40\% = \frac{40}{100} = 0.40$

Step4: Simplify the fraction

Reduce $\frac{40}{100}$ by GCD 20: $\frac{40 \div 20}{100 \div 20} = \frac{2}{5}$

Answer:

1. Shade 40 total cells in the grid (e.g., the top 4 full rows, which is 4×10=40 cells)
2. $40\% = 0.40$
3. $40\% = \frac{2}{5}$
