Answer 1

Увеличение на 40% - это *1,4
620*1,4=868.
В чем вопрос?
 Можно добавить, что 40% от 620= 620*40/100=248 - это прирост числа чеников.
620+248=868

Answer 2

Calculation of the Number of Students at the End of the School Year

To calculate the number of students at the end of the school year, we need to determine the increase in the number of students due to the increase in the population of the district.

Given: - Number of students at the beginning of the school year: 620 - Increase in the number of students due to the increase in the population: 40%

To find the number of students at the end of the school year, we can use the following formula:

Number of students at the end of the school year = Number of students at the beginning of the school year + (Increase in the number of students * Number of students at the beginning of the school year)

Let's calculate it step by step:

1. Calculate the increase in the number of students: - Increase in the number of students = 40% of 620 - Increase in the number of students = 0.4 * 620 - Increase in the number of students = 248

2. Calculate the number of students at the end of the school year: - Number of students at the end of the school year = 620 + 248 - Number of students at the end of the school year = 868

Therefore, the correct answer is 2) 868 students.
