How are percentages calculated?
Here is an example of how percentages are calculated:
Let’s say you have a class of 25 students, and 15 of them passed the test. To find the percentage of students who passed, you would follow these steps:
Divide the part by the whole:
Part = 15 (number of students who passed)
Whole = 25 (total number of students)
15 ÷ 25 = 0.6
Multiply by 100:
0.6 x 100 = 601
Therefore, 60% of the students passed the test.
