If there are 30 students in a class and 24 are present, how many are absent?

To determine the number of students who are absent, you can subtract the number of students present from the total number of students in the class.

Here, there are 30 students in total. If 24 of those students are present, the calculation is straightforward:

Total students - Present students = Absent students 30 - 24 = 6

This calculation shows that 6 students are absent. Therefore, the correct answer aligns with this calculation. It highlights the importance of simple arithmetic in solving problems effectively.
