To calculate the percentage of students who received each grade, we first need the total number of students. Here’s the breakdown:

• A = 5
• B = 10
• C = 22
• D = 4
• F = 2

Total number of students:

$\text{Total} = 5 + 10 + 22 + 4 + 2 = 43$

Now, we calculate the percentage for each grade:

1. A: $\text{Percentage} = \left( \frac{5}{43} \right) \times 100 \approx 11.6\%$

2. B: $\text{Percentage} = \left( \frac{10}{43} \right) \times 100 \approx 23.3\%$

3. C: $\text{Percentage} = \left( \frac{22}{43} \right) \times 100 \approx 51.2\%$

4. D: $\text{Percentage} = \left( \frac{4}{43} \right) \times 100 \approx 9.3\%$

5. F: $\text{Percentage} = \left( \frac{2}{43} \right) \times 100 \approx 4.7\%$

Summary of Percentages:

• A: 11.6%
• B: 23.3%
• C: 51.2%
• D: 9.3%
• F: 4.7%
