Problem Analysis

We are given that there are 30 students in the 4A class. Out of these students, 3/10 are involved in the Young Naturalists Club, and 5/10 are involved in the Environmental Club. We need to find the total number of students involved in these clubs.

Solution

To find the number of students in each club, we can multiply the total number of students by the fraction representing the proportion of students in each club.

Let's calculate the number of students in each club:

1. Young Naturalists Club: 3/10 * 30 = 9 students 2. Environmental Club: 5/10 * 30 = 15 students

To find the total number of students involved in these clubs, we can add the number of students in each club:

9 students (Young Naturalists Club) + 15 students (Environmental Club) = 24 students

Therefore, a total of 24 students are involved in the Young Naturalists Club and the Environmental Club.

Answer

The total number of students involved in the Young Naturalists Club and the Environmental Club is 24 students.
