Question

1. tracey is reading a novel for her english class. she shaded a grid to show how much of the book she has read so far. what percent of the grid is shaded?

a 6%
c 60%
b 40%
d 600%

Explanation:

Step1: Count total grid cells

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

Step2: Count shaded cells

Count shaded cells: each of the first 6 columns has 10 shaded cells, so $6 \times 10 = 60$

Step3: Calculate percentage

Percent shaded = $\frac{\text{Shaded Cells}}{\text{Total Cells}} \times 100\% = \frac{60}{100} \times 100\% = 60\%$

Answer:

C. 60%
