Calculation of the Number of Students in the Third School

To calculate the number of students in the third school, we need to consider the information provided about the first and second schools. Let's break down the given information:

- The first school has 1725 students. - The second school has 639 more students than the first school. - The third school has 125 fewer students than the combined number of students in the first and second schools.

To find the number of students in the third school, we can follow these steps:

1. Calculate the total number of students in the first and second schools: - The second school has 639 more students than the first school, so the total number of students in the first and second schools is 1725 + 639 = 2364.

2. Subtract 125 from the total number of students in the first and second schools to find the number of students in the third school: - The number of students in the third school is 2364 - 125 = 2239.

Therefore, there are 2239 students in the third school.
