Question

what percentage of the shape is pink?
write your answer using a percent sign (%).

Explanation:

Step1: Count total grid cells

The grid is 10x10, so total cells: $10 \times 10 = 100$

Step2: Count white grid cells

White cells: $2 + 10 + 10 = 22$

Step3: Calculate pink cell count

Pink cells = Total - White: $100 - 22 = 78$

Step4: Convert to percentage

Since total cells = 100, pink percentage = $\frac{78}{100} \times 100\% = 78\%$

Answer:

78%
