There are 28 7th graders in Ms. Thomas's homeroom. Seven of the students are absent today. What percent of the class was absent?
25
7/28=0.25*100=25%
To find the percentage of the class that was absent, you need to divide the number of absent students by the total number of students, and then multiply by 100.
First, you need to calculate the number of absent students by subtracting the number of absent students from the total number of students:
Number of absent students = Total number of students - Number of absent students
Number of absent students = 28 - 7 = 21
Next, you can find the percentage by dividing the number of absent students by the total number of students, and then multiplying by 100:
Percentage of absent students = (Number of absent students / Total number of students) * 100
Percentage of absent students = (21 / 28) * 100 = 75%
Therefore, 75% of the class was absent.
