Example 1: Calculate Student Attendance Percentage
A student attended 45 classes out of 80 total classes.
Steps:
- Divide attended classes by total classes: 45 ÷ 80 = 0.5625
- Convert to percentage: 0.5625 × 100 = 56.25%
Result: The student’s attendance percentage is 56.25%, which is below the common 75% requirement.
Example 2: Calculate Required Attendance to Reach 75%
A student has attended 45 out of 80 classes and needs at least 75% attendance.

- Convert required percentage to decimal: 75% ÷ 100 = 0.75
- Calculate required total attendance: 0.75 × total classes = required attendance
- Determine additional classes needed: (0.75 × 80 − 45) ÷ (1 − 0.75) = 60
Result: The student needs to attend 15 more consecutive classes to reach 75% attendance.
Example 3: Calculate Employee Absenteeism Rate
A company has 50 employees working 20 days per month. Employees missed 50 total days.
Steps:
- Calculate total possible workdays: 50 × 20 = 1,000
- Divide absent days by total workdays: 50 ÷ 1,000 = 0.05
- Convert to percentage: 0.05 × 100 = 5%
Result: The company’s absenteeism rate is 5%.
Example 4: Calculate Event Attendance Percentage
A workshop had 100 registered participants, but only 75 attended.
