11. Twenty-four students in a class are right- handed and 6 are left-handed. If these figures represent the entire class, what percent is left-handed? (A) \( 15 \% \) (B) \( 25 \% \) (C) \( 20 \% \) (D) \( 30 \% \)

To find the percentage of left-handed students in the class, we first need to determine the total number of students. The total number of students is: \[ 24 \text{ (right-handed)} + 6 \text{ (left-handed)} = 30 \text{ (total students)} \] Next, we calculate the percentage of left-handed students: \[ \text{Percentage of left-handed students} = \left( \frac{\text{Number of left-handed students}}{\text{Total number of students}} \right) \times 100 \] Substituting the values: \[ \text{Percentage of left-handed students} = \left( \frac{6}{30} \right) \times 100 \] Calculating the fraction: \[ \frac{6}{30} = 0.2 \] Now, multiplying by 100 to get the percentage: \[ 0.2 \times 100 = 20\% \] Thus, the percentage of left-handed students is \( 20\% \). The correct answer is (C) \( 20\% \).
