B. 15 students
C. 30 students
D. 20 students

Answer 1

The correct option is A). To find the total number of students in Mr. Kim's art class, divide the number of students who used watercolors (10) by the percentage they represent (40%), yielding a total of 25 students.

Step-by-step explanation:

The question is asking us to determine the total number of students in Mr. Kim's art class, knowing that 10 students represent 40% of the class. We can calculate the total number of students by dividing the number of students who used watercolors (10 students) by the percentage they represent (40%). This is a basic percentage problem.

Here's the step-by-step calculation:

Convert the percentage to its decimal form by dividing by 100: 40% = 0.40.

Divide the number of students using watercolors by this decimal to find the total number of students: Total number of students = 10 students / 0.40.

Perform the division: Total number of students = 25.

Therefore, the answer is A. 25 students.
