Answer 1

Пусть кол-во учащихся 4 классов x чел,
тогда кол-во учащихся 5 классов x - 6 чел
x + x - 6 = 52
2x = 58
x = 29
29 - 6 = 23 учащихся

Answer 2

Calculation of the Number of Fifth Graders in the School Camp

To calculate the number of fifth graders who attended the school camp last year, we need to use the information provided.

According to the information given, there were 52 students from the fourth and fifth grades combined. Additionally, there were 6 fewer fifth graders than fourth graders.

Let's assume the number of fourth graders is represented by x. Therefore, the number of fifth graders would be x - 6.

To find the total number of students, we can add the number of fourth graders and the number of fifth graders:

x + (x - 6) = 52

Simplifying the equation:

2x - 6 = 52

Adding 6 to both sides:

2x = 58

Dividing both sides by 2:

x = 29

Therefore, there were 29 fourth graders and 29 - 6 = 23 fifth graders who attended the school camp last year.

Answer:

There were 23 fifth graders who attended the school camp last year.
