Step-by-step explanation:
To solve this problem you mmust apply the steps shown below:
1. You know that there is a total of 100 students, then you can say that the 100% is 100 students.
2. Then, to calculate how much would 40% be, you must multiply 100 students by 40% which you rewrite as a decimal by dividing it by 100, as following:
