Question

В 8 классах учатся 100 человек, 54 человека посещают кружок по математике, 46 человек посещают кружок по английскому языку, 25 посещают оба кружка. Сколько учеников не посещают ни одного кружка? Поясните ответ, пожалуйста.

Answer 1

ответ 46+54=100 , но так как 25 чел. посещают оба кружка тогда 100-25=75 . 75 человек посещают какие либо кружки. и 25 не посещают ни одного потому что 100-75=25

Answer 2

Problem Analysis

We are given the following information: - There are 100 students in the 8th grade. - 54 students attend a math club. - 46 students attend an English club. - 25 students attend both clubs.

We need to find the number of students who do not attend either club.

Solution

To find the number of students who do not attend either club, we can subtract the number of students who attend at least one club from the total number of students.

Let's calculate it step by step:

1. Find the number of students who attend at least one club: - The number of students who attend the math club is 54. - The number of students who attend the English club is 46. - The number of students who attend both clubs is 25. - To find the total number of students who attend at least one club, we can add the number of students who attend the math club and the number of students who attend the English club, and then subtract the number of students who attend both clubs: 54 + 46 - 25 = 75.

2. Find the number of students who do not attend either club: - To find the number of students who do not attend either club, we can subtract the number of students who attend at least one club from the total number of students: 100 - 75 = 25.

Therefore, there are 25 students who do not attend either the math club or the English club.

Answer

There are 25 students who do not attend either the math club or the English club.
