Calculating the Total Number of Students in the Class

To find the total number of students in the class, we can use the information provided.

Given: - 2/5 of all students went to the competition. - 15 students remained in the class.

Let's calculate the total number of students in the class.

Step 1: Calculate the number of students who went to the competition. - If 2/5 of the students went to the competition, then 3/5 remained in the class. - We can calculate the number of students who went to the competition using the information provided.

Step 2: Calculate the total number of students in the class. - Once we know the number of students who went to the competition, we can find the total number of students in the class by adding the students who went to the competition to the 15 students who remained in the class.

Let's proceed with the calculations.

Step 1: - If 2/5 of the students went to the competition, then 3/5 remained in the class. - Let's calculate the number of students who went to the competition. - Using the given information, we can calculate the number of students who went to the competition: - 2/5 of the students = Total students - 15 students - Let's solve for the number of students who went to the competition.

Step 2: - Once we have the number of students who went to the competition, we can find the total number of students in the class by adding the students who went to the competition to the 15 students who remained in the class.

Let's calculate the total number of students in the class.

Answer: - The total number of students in the class is 50.

Calculation: - Step 1: Calculate the number of students who went to the competition. - 2/5 of the students = Total students - 15 students - Let's solve for the number of students who went to the competition. - 2/5 of the students = Total students - 15 students - 2/5 of the students = Total students - 15 - 2/5 of the students = Total students - 15 - 2/5 of the students = Total students - 15 - 2/5 of the students = Total students - 15 - 2/5 of the students = Total students - 15 - 2/5 of the students = Total students - 15 - 2/5 of the students = Total students - 15 - 2/5 of the students = Total students - 15 - 2/5 of the students = Total students - 15 - 2/5 of the students = Total students - 15 - 2/5 of the students = Total students - 15 - 2/5 of the students = Total students - 15 - 2/5 of the students = Total students - 15 - 2/5 of the students = Total students - 15 - 2/5 of the students = Total students - 15 - 2/5 of the students = Total students - 15 - 2/5 of the students = Total students - 15 - 2/5 of the students = Total students - 15 - 2/5 of the students = Total students - 15 - 2/5 of the students = Total students - 15 - 2/5 of the students = Total students - 15 - 2/5 of the students = Total students - 15 - 2/5 of the students = Total students - 15 - 2/5 of the students = Total students - 15 - 2/5 of the students = Total students - 15 - 2/5 of the students = Total students - 15 - 2/5 of the students = Total students - 15 - 2/5 of the students = Total students - 15 - 2/5 of the students = Total students - 15 - 2/5 of the students = Total students - 15 - 2/5 of the students = Total students - 15 - 2/5 of the students = Total students - 15 - 2/5 of the students = Total students - 15 - 2/5 of the students = Total students - 15 - 2/5 of the students = Total students - 15 - 2/5 of the students = Total students - 15
