Question

В молодом лесу растёт 800 сосен ёлочек на 100 больше а берёзок на 200 меньше чем сосен и ёлочек вместе сколько берёзок растёт в лесу

Answer 1

1500 Березок растет в лесу

Answer 2

1) 800+100= 900 - елочек
2) 800+900= 1700 - елочеки и сосен вместе
3) 1700-200= 1500 - березок

Answer 3

Calculating the Number of Birch Trees in the Forest

To calculate the number of birch trees in the forest, we can use the information provided about the number of pine trees and fir trees.

Given: - There are 800 pine trees and fir trees in the young forest. - There are 100 more fir trees than birch trees. - There are 200 fewer birch trees than the combined total of pine trees and fir trees.

Let's denote: - P = number of pine trees - F = number of fir trees - B = number of birch trees

We know that: 1. P + F = 800 2. F = B + 100 3. B = (P + F) - 200

Calculating the Number of Birch Trees

Using the given information, we can solve for the number of birch trees:

From equation 1, we have: P = 800 - F

Substitute P in equation 3: B = (800 - F) + F - 200 B = 600 - F

Substitute F from equation 2: B = 600 - (B + 100) B = 600 - B - 100 2B = 500 B = 250

Therefore, there are 250 birch trees in the forest.
