If a class has 40 students and 25% of them are absent, how many students are present?

If a class has 40 students and 25% of them are absent, how many students are present?

Step 1: Find out how many students are in the class. There are 40 students.
Step 2: Calculate 25% of the total number of students. To do this, multiply 40 by 0.25 (which is the decimal form of 25%).
Step 3: 40 multiplied by 0.25 equals 10. This means 10 students are absent.
Step 4: To find out how many students are present, subtract the number of absent students from the total number of students. So, 40 - 10 equals 30.
Step 5: Therefore, there are 30 students present in the class.
