To find the percentage of students at the school who need special diets, we follow these steps:
1. Identify the total number of students needing special diets and the total number of students at the school:
- Students needing special diets: 33
- Total number of students at school: 300
2. Set up the fraction representing the students needing special diets out of the total number of students:
[tex]\[
\frac{33 \text{ students needing special diets}}{300 \text{ total students}}
\][/tex]
3. Convert the fraction to a decimal by dividing the numerator by the denominator:
[tex]\[
\frac{33}{300} = 0.11
\][/tex]
4. Convert the decimal to a percentage by multiplying by 100:
[tex]\[
0.11 \times 100 = 11\%
\][/tex]
Thus, based on the chart, [tex]\( 11\% \)[/tex] of the students at the school need special diets. The correct option is:
11 percent
