Answer 1

1 способ:
1) 48 + 56 = 104 (чел.) - мужчины и женщины
2) 130 - 104 = 26 (чел.)
2 способ:
1) 130 - 48 = 82 (чел.) - мужчины и дети
2) 82 - 56 = 26 (чел.)
3 способ:
1) 48 + 56 + ? = 130
2) 104 + ? = 130
3) 130 - 104 = 26
Ответ: 26 детей

Answer 2

Solution 1: Using Basic Arithmetic

To solve the problem of determining the number of children who came on the excursion, we can use basic arithmetic.

Given: - Total number of tourists: 130 - Number of women: 48 - Number of men: 56

To find the number of children, we can subtract the number of women and men from the total number of tourists:

Number of children = Total number of tourists - Number of women - Number of men

Substituting the given values:

Number of children = 130 - 48 - 56

Number of children = 26

Therefore, 26 children came on the excursion.

Solution 2: Using Proportions

Another way to solve the problem is by using proportions.

Given: - Total number of tourists: 130 - Number of women: 48 - Number of men: 56

We can set up a proportion to find the number of children:

(Number of children) / (Total number of tourists) = (Number of children) / (Number of women + Number of men)

Substituting the given values:

(Number of children) / 130 = (Number of children) / (48 + 56)

Cross-multiplying:

(Number of children) * (48 + 56) = (Number of children) * 130

48 * (Number of children) + 56 * (Number of children) = 130 * (Number of children)

104 * (Number of children) = 130 * (Number of children)

Dividing both sides by (Number of children):

104 = 130

Since the equation is not true, it means that there is no unique solution using proportions. Therefore, we cannot determine the number of children using this method.

Solution 3: Using Algebra

We can also solve the problem using algebra.

Given: - Total number of tourists: 130 - Number of women: 48 - Number of men: 56

Let's assume the number of children is represented by 'x'.

We can set up an equation based on the given information:

x + 48 + 56 = 130

Combining like terms:

x + 104 = 130

Subtracting 104 from both sides:

x = 130 - 104

x = 26

Therefore, 26 children came on the excursion.

In conclusion, there are three ways to solve the problem of determining the number of children who came on the excursion: 1. Using basic arithmetic: 26 children came on the excursion. 2. Using proportions: There is no unique solution using this method. 3. Using algebra: 26 children came on the excursion.
