Answer 3

Answer:

a) 24 students study in classes 4 and 5.

b) There are 30 students in the class.

Explanation:

To solve this problem, we can use the information provided in the question and apply some basic math.

a) We know that 3/4 of the class (24 students) study in classes 4 and 5. This is calculated by multiplying the total number of students by 3/4:

24 = (3/4) * Total number of students

So, to find the total number of students, we can use the formula:

Total number of students = 24 / (3/4) = 24 * (4/3) = 32

Therefore, 24 students study in classes 4 and 5.

b) We are given that 3/5 of the class (18 students) study without getting a grade of 3. We can use this information to find the total number of students in the class:

18 = (3/5) * Total number of students

So, to find the total number of students, we can use the formula:

Total number of students = 18 / (3/5) = 18 * (5/3) = 30

Therefore, 30 students are in the class.
