Calculating the Number of Students in the Class

To calculate the number of students in the class who study on "4" and "5", we can use the information provided in the question and the given proportion of excellent students and the rest of the students.

Given: - Excellent students make up 1/9 of all students in the class. - The rest of the students (non-excellent) are divided into those who study on "4" and "5".

Let's denote: - Total number of students in the class as T - Number of excellent students as E - Number of non-excellent students as N - Number of non-excellent students who study on "4" and "5" as X

From the given information: 1. E = 1/9 * T 2. N = T - E 3. X = 1/2 * N

Calculating the Number of Students Studying on "4" and "5"

Now, we can use the above equations to calculate the number of students who study on "4" and "5".

First, we'll calculate the number of excellent students and then use it to find the number of non-excellent students and, subsequently, the number of students studying on "4" and "5".

Let's proceed with the calculations.
