The meaning of the percentage.

The video tutorial explains how to calculate the success and failure percentages of students in exams. It compares the success rates of two classes, one with a 100% success rate and another with a 50% success rate. The tutorial demonstrates the calculation method by multiplying the success percentage by the total number of students. An example is provided where the success percentage is calculated for a class with 4 successful students out of 10, resulting in a 40% success rate.
