So the number of pine trees is 5x and the number of hardwood trees is 7x which gives the ratio of %285x%29%2F%287x%29=5%2F7
So together the total number of trees is 5x%2B7x=12x
The percentage of pine trees would be %28%285x%29%2F%2812x%29%29%2A100=500%2F12=41.7
The percentage of hardwood trees would be %28%287x%29%2F%2812x%29%29%2A100=700%2F12=58.3
