In one class, there are 15 boys and 30 girls. Approximately what percentage of the students in the class are boys?
34%
15 boys out of 45 students
percentage of boys = 1500%/45 = 33 1/3%
To find the percentage of boys in the class, you need to determine the ratio of boys to the total number of students and then multiply it by 100.
First, add the number of boys and girls to get the total number of students in the class: 15 (boys) + 30 (girls) = 45 (students).
Next, find the ratio of boys to the total number of students: 15 (boys) / 45 (students) = 1/3.
Finally, multiply the ratio by 100 to convert it to a percentage: (1/3) * 100 = 33.33%.
Therefore, approximately 33.33% of the students in the class are boys.
