Final answer:
To find out how many students are in the drama club at a school with 500 students, multiply the total number of students by 0.30 (which is the decimal form of 30%). The calculation is 500 x 0.30 = 150 students.
Step-by-step explanation:
To calculate the number of students in the drama club at a school with 500 students where 30% of them are in the drama club, we use a simple percentage calculation. First, we establish that 30% is the same as 0.30 when written as a decimal. Then, we multiply the total number of students, which is 500, by 0.30. This mathematical operation will give us the exact number of students who are in the drama club.
500 students × 0.30 (30%) = 150 students
Therefore, there are 150 students in the drama club at the school.
