Calculating the Number of Trees to Plant

To calculate the number of trees needed to be planted to reach 70% of linden trees, we can use the information provided.

Given: - Total trees planted: 72 - Percentage of linden trees: 62.5%

We can start by finding the number of linden trees currently planted and then calculate the additional number of linden trees needed to reach 70%.

Step 1: Calculate the number of linden trees currently planted: - Total trees planted: 72 - Percentage of linden trees: 62.5%

Using the given information, we can calculate the number of linden trees currently planted: - Number of linden trees = Total trees * Percentage of linden trees - Number of linden trees = 72 * 62.5%

Let's calculate the number of linden trees currently planted.

Step 2: Calculate the additional number of linden trees needed to reach 70%: - Desired percentage of linden trees: 70%

Now, we can calculate the additional number of linden trees needed to reach 70% of all trees.

Calculation

- Number of linden trees currently planted: 72 * 62.5% - Additional number of linden trees needed to reach 70%: (Total trees * 70%) - (Number of linden trees currently planted)

Let's perform the calculations to find the number of linden trees currently planted and the additional number of linden trees needed to reach 70%.

Results

- Number of linden trees currently planted: 45 linden trees [[2 #]] - Additional number of linden trees needed to reach 70%: 7 linden trees

Therefore, to reach 70% linden trees, 7 additional linden trees need to be planted.
