Problem Analysis

In the given problem, there are 36 students in the class. Out of these, 8 students have received a grade of "5" in mathematics, 12 students have received a grade of "4", and the remaining students have received a grade of "3". We need to create a pie chart to represent these grades.

Solution

To create a pie chart, we need to calculate the percentage of students who received each grade. Let's calculate the percentages:

- Number of students who received a grade of "5": 8 - Number of students who received a grade of "4": 12 - Number of students who received a grade of "3": 36 - 8 - 12 = 16

Now, let's calculate the percentages:

- Percentage of students who received a grade of "5": (8 / 36) * 100 = 22.22% - Percentage of students who received a grade of "4": (12 / 36) * 100 = 33.33% - Percentage of students who received a grade of "3": (16 / 36) * 100 = 44.44%

Pie Chart Representation

We can represent these percentages in a pie chart. The pie chart will have three sections, each representing a grade. The size of each section will be proportional to the percentage of students who received that grade.

Here is the representation of the pie chart:


In the pie chart, the section representing the grade "5" will occupy approximately 22.22% of the chart, the section representing the grade "4" will occupy approximately 33.33% of the chart, and the section representing the grade "3" will occupy approximately 44.44% of the chart.

Please note that the image provided above is just a representation. You can create a similar pie chart using any graphing software or by hand.
