Question

. Во время озеленения школьной территории посадили каштаны, липы и березы. Каштанов посадили 10 деревьев, что составляет 2 /5 посаженных лип. Количество берез составляет седьмую посаженых каштанов и лип. Какое общее количество лип и берез посадили?

Answer 1

1)10÷2/5=10×5/2=25 (д)- липы
2)10+25=35 (д)- липы и каштаны вместе
3)35×1/7=5 (д)- березы
4)25+5=30 (д)- липы и березы вместе.

Answer 2

Calculation of the Number of Lime and Birch Trees Planted

To determine the total number of lime and birch trees planted during the greening of the school grounds, we need to analyze the given information.

Let's break down the information step by step:

1. The number of chestnut trees planted is 10. 2. This number represents 2/5 of the total number of lime trees planted. 3. The number of birch trees planted is 1/7 of the combined number of chestnut and lime trees.

Now, let's calculate the number of lime trees:

1. We know that the number of chestnut trees is 10. 2. Since this number represents 2/5 of the total number of lime trees, we can set up the equation: (2/5) * Total Lime Trees = 10. 3. Solving this equation, we find that the total number of lime trees is 25.

Next, let's calculate the number of birch trees:

1. We know that the number of birch trees is 1/7 of the combined number of chestnut and lime trees. 2. The combined number of chestnut and lime trees is 10 (chestnut trees) + 25 (lime trees) = 35 trees. 3. Therefore, the number of birch trees is (1/7) * 35 = 5 trees.

Finally, let's calculate the total number of lime and birch trees:

1. The total number of lime trees is 25. 2. The total number of birch trees is 5. 3. Adding these two numbers together, we find that the total number of lime and birch trees planted is 25 + 5 = 30.

Therefore, the total number of lime and birch trees planted during the greening of the school grounds is 30.
