2)312-208=104(экспонатов)-собрали уч
Ответ: 104 экспонатов

Answer 2

This is a math problem that asks how many exhibits were collected by students in a school museum of military glory. The problem gives the following information:

- The total number of exhibits in the museum is 312. - Two-thirds of the exhibits were sold to the museum by veterans. - The remaining exhibits were collected by students.

To solve this problem, we need to find the fraction of the exhibits that were collected by students and then multiply it by the total number of exhibits. We can use the following steps:

- First, we need to find the fraction of the exhibits that were sold by veterans. Since two-thirds of the exhibits were sold by veterans, the fraction is 2/3. - Next, we need to find the fraction of the exhibits that were collected by students. Since the fraction of the exhibits that were sold by veterans and the fraction of the exhibits that were collected by students add up to 1, we can subtract the fraction of the exhibits that were sold by veterans from 1 to get the fraction of the exhibits that were collected by students. The fraction is 1 - 2/3 = 1/3. - Then, we need to multiply the fraction of the exhibits that were collected by students by the total number of exhibits to get the number of exhibits that were collected by students. The number is 1/3 * 312 = 104.

Therefore, the answer is that 104 exhibits were collected by students.
