Question

which model shows 80%?

Explanation:

Step1: Calculate first model's percentage

Total parts = 4, shaded parts = 3.
Percentage = $\frac{3}{4} \times 100\% = 75\%$

Step2: Calculate second model's percentage

Total parts = 8, shaded parts = 7.
Percentage = $\frac{7}{8} \times 100\% = 87.5\%$

Step3: Calculate third model's percentage

Total parts = 5, shaded parts = 4.
Percentage = $\frac{4}{5} \times 100\% = 80\%$

Answer:

The third model (the bottom one with 4 shaded parts out of 5 total parts) shows 80%.
