Final answer:
To find the total number of students at Harris Middle School, set up a proportion using the given percentage and number of students on the yearbook committee. Solving this reveals that there are 300 students at Harris Middle School.
Step-by-step explanation:
The student asked: If 10% of the students at Harris Middle School are on the yearbook committee and there are 30 students on the committee, how many students are at Harris Middle School in total?
To answer this, we set up an equation based on the percentage. Since 10% represents the yearbook committee members, we can express this as 10/100. So, if 30 students represent 10% of the total number of students, we write:
10/100 = 30/Total Students
To find the number of total students, we cross-multiply and divide:
10 * Total Students = 100 * 30
Total Students = (100 * 30) / 10
Total Students = 3000 / 10
Total Students = 300
Therefore, there are 300 students at Harris Middle School.
