Final answer:
To find the percentage of students with brown eyes, we need to determine the size of the brown section in the pie chart. We can count the number of students with brown eyes and divide it by the total number of students, then multiply by 100 to get the percentage.
Step-by-step explanation:
The given question asks for the approximate percentage of students with brown eyes based on a pie chart. To find this percentage, we need to determine the size of the brown section in the pie chart. Since the chart represents 30 students, we can count the number of students with brown eyes and divide it by 30, then multiply by 100 to get the percentage.
Let's say the brown section represents 6 out of 30 students. To find the percentage, we can write it as a fraction: 6/30. The fraction can be simplified to 1/5. To convert it to a percentage, multiply by 100: 1/5 x 100 = 20%.
So approximately 20% of the students have brown eyes.
