Problem Analysis

To solve this problem, we need to determine the number of tables in the Sunday school based on the given information. We know that there were 129 boys playing and three times fewer girls. Once the children saw the teacher, they immediately sat down at the tables, leaving one table for the teacher. We also know that each table, except the one for the teacher, had 4 students sitting at it.

Solution

Let's break down the problem step by step:

1. We know that there were 129 boys playing and three times fewer girls. To find the number of girls, we need to divide the number of boys by 3: 129 / 3 = 43 girls.

2. Now, let's calculate the total number of students. We add the number of boys and girls together: 129 boys + 43 girls = 172 students.

3. We also know that each table, except the one for the teacher, had 4 students sitting at it. To find the number of tables, we divide the total number of students by 4: 172 students / 4 students per table = 43 tables.

4. Finally, we subtract 1 table for the teacher: 43 tables - 1 table = 42 tables.

Therefore, there were 42 tables in the Sunday school.

Conclusion

Based on the given information, there were 42 tables in the Sunday school if there were 129 boys playing and three times fewer girls, and each table, except the one for the teacher, had 4 students sitting at it.

Answer 4

Calculating the Number of Tables in the Sunday School

To calculate the number of tables in the Sunday school, we can use the information provided in the question. Let's break it down step by step.

1. Number of Boys and Girls Playing: - There were 129 boys playing. - The number of girls was three times less than the number of boys.

2. Seating Arrangement: - As soon as they saw the teacher, they immediately sat down at the tables, leaving one table for the teacher. - Each table (except the one for the teacher) had 4 students seated.

Solution

1. Number of Girls: - Since the number of girls was three times less than the number of boys, the number of girls can be calculated as 129 boys / 3 = 43 girls.

2. Total Number of Students: - Total number of students = Number of boys + Number of girls = 129 boys + 43 girls = 172 students.

3. Number of Tables: - Each table (except the one for the teacher) had 4 students seated. - So, the number of tables can be calculated as the total number of students (excluding the teacher's table) divided by 4.

- Number of tables = (Total number of students - 1) / 4 - Number of tables = (172 - 1) / 4 - Number of tables = 171 / 4 - Number of tables = 42 remainder 3

Therefore, there were 42 tables in the Sunday school, with 3 students left over.
