Pear Tree: Apple = 5: 4

The first method: So pear trees account for 5/9-2 16 = 180 of 540.

Then the apple is 540-216-180 =144.

There are more pear trees than apple trees 180- 144=36.

In the second method (continued from 5: 4), there are more pear trees than apples. After subtracting peach trees,1/9 = (540-216)/9 = 36 (pieces).
