If you would like to know how many pine and maple trees will be planted, you can calculate this using the following steps:
2 pine trees + 3 maple trees = 5 trees
300 trees / 5 trees = 300 / 5 = 60
pine trees: 2 * 60 = 120
maple trees: 3 * 60 = 180
The correct result would be 120 pine trees and 180 maple trees.
