Answer:
The number of ash trees = 45 trees
Explanation:
the number of maple trees ash trees and elm trees are in the ratio 2 : 5 : 8
Let the number of maple trees be 2x
Let the number of ash trees be 5x
Let the number of elm trees be 8x
If there are 54 more elm trees than maple trees, then they can be represented as
8x - 2x = 54
6x = 54
x = 9
The number of ash trees = 5x = 5 * 9 = 45 trees
