Question

В честь дня земли в парке посадили 238 деревьев.Дети посадили половину того, что посадили женщины, а женщины посадили половину того, что посадили мужчины. Сколько деревьев посадили дети сколько деревьев посадили женщины и сколько деревьев посадили мужчины?

Answer 1

То что посадили дети - х
женщины - 2х
мужчины - 4х
х+2х+4х = 238
7х = 238
х = 34
значит
дети посадили 34 дерева
женщины - 68
мужчины - 136

Answer 2

Problem Analysis

To solve this problem, we need to determine how many trees were planted by children, women, and men based on the given information. Let's break down the information provided:

- In honor of Earth Day, 238 trees were planted in the park. - Children planted half of what women planted. - Women planted half of what men planted.

We need to find the number of trees planted by children, women, and men.

Solution

Let's solve this problem step by step:

1. Let's assume the number of trees planted by men is x. 2. According to the given information, women planted half of what men planted, so the number of trees planted by women is x/2. 3. Children planted half of what women planted, so the number of trees planted by children is (x/2)/2 or x/4.

Now, we can set up an equation to solve for x:

x + x/2 + x/4 = 238

Let's solve this equation to find the value of x.

Calculation

To solve the equation x + x/2 + x/4 = 238, we can multiply the entire equation by the least common denominator (LCD), which is 4:

4x + 2x + x = 238 * 4

Simplifying the equation:

7x = 952

Dividing both sides of the equation by 7:

x = 952 / 7

Calculating the value of x:

x = 136

Answer

Based on the given information, the number of trees planted by children is x/4, which is 136/4 = 34.

The number of trees planted by women is x/2, which is 136/2 = 68.

The number of trees planted by men is x, which is 136.

Therefore, the number of trees planted by children is 34, by women is 68, and by men is 136.

Conclusion

In honor of Earth Day, 238 trees were planted in the park. Children planted 34 trees, women planted 68 trees, and men planted 136 trees.
