Answer 3

Calculating the Percentage of Fir Trees in the Palace Park

To calculate the percentage of fir trees in the palace park, we can use the information provided. Let's denote the number of pine trees as P and the number of fir trees as F.

Given: - The total number of pine and fir trees is 2. - The number of fir trees is 12 less than the number of pine trees.

We can represent this information as the following system of equations: 1. F + P = 2 (total number of trees) 2. F = P - 12 (number of fir trees is 12 less than the number of pine trees)

Solving the System of Equations

Substituting the value of F from equation 2 into equation 1: P - 12 + P = 2 2P - 12 = 2 2P = 2 + 12 2P = 14 P = 7

So, the number of pine trees (P) is 7.

Substituting the value of P back into equation 2: F = 7 - 12 F = -5

This result doesn't make sense in the context of the problem, as the number of trees cannot be negative. It seems there might be a mistake in the given information or the problem statement.

Unfortunately, based on the provided information, it's not possible to accurately calculate the percentage of fir trees in the palace park. If there's additional information or if there's a specific approach you'd like to take to solve this problem, please feel free to share it!
