Answer:
3/5
Explanation:
Let the number of beech trees be 3x and the number of maple trees be 2x (since the ratio of beech to maple is 3.2 : 1, we can choose any common factor for the numbers of beech and maple trees).
So, the total number of trees is 3x + 2x = 5x.
We are given that the total number of trees is 5040, so:
5x = 5040
x = 1008
Therefore, the number of beech trees is 3x = 3(1008) = 3024, and the number of maple trees is 2x = 2(1008) = 2016.
The fraction of trees that are beech is:
3024 / (3024 + 2016) = 3024 / 5040
To simplify this fraction, we can divide both the numerator and denominator by their greatest common factor, which is 1008:
3024 / 5040 = (3024 ÷ 1008) / (5040 ÷ 1008) = 3 / 5
Therefore, the fraction of trees that are beech is 3/5.
