Answer 1

2 класс: 68 человек(4*17) 3 класс: 72 человека(6*12) 4 класс:75 человек(15*5) Всего:215 человек(68+72+75)

Answer 2

Calculation of the Number of Students in Each Grade

To determine the number of students in each grade and the total number of students who participated in the math Olympiad, we need to add up the number of students in each grade.

For the second grade: - The students were divided into 4 groups, with each group consisting of 17 students. - Therefore, the total number of students in the second grade is 4 groups x 17 students/group = 68 students.

For the third grade: - The students were divided into 6 groups, with each group consisting of 12 students. - Therefore, the total number of students in the third grade is 6 groups x 12 students/group = 72 students.

For the fourth grade: - The students were divided into 5 groups, with each group consisting of 15 students. - Therefore, the total number of students in the fourth grade is 5 groups x 15 students/group = 75 students.

Calculation of the Total Number of Students in the Math Olympiad

To calculate the total number of students who participated in the math Olympiad, we need to add up the number of students from each grade.

- The total number of students in the second, third, and fourth grades is 68 + 72 + 75 = 215 students.

Therefore, the total number of students who participated in the math Olympiad is 215 students.
