Problem Analysis

We are given that in a garden, there are apple trees, pear trees, and plum trees. The apple trees make up 8/15 of all the trees, the pear trees make up 4/15 of all the trees, and there are 12 plum trees. We need to find the total number of trees in the garden, as well as the number of apple trees and pear trees.

Solution

Let's assume the total number of trees in the garden is x.

According to the given information: - The apple trees make up 8/15 of all the trees, so there are (8/15) * x apple trees. - The pear trees make up 4/15 of all the trees, so there are (4/15) * x pear trees. - There are 12 plum trees.

To find the total number of trees in the garden, we can set up the following equation:

(8/15) * x + (4/15) * x + 12 = x

Simplifying the equation:

(8/15 + 4/15) * x + 12 = x

(12/15) * x + 12 = x

12/15 * x = x - 12

12x = 15x - 180

15x - 12x = 180

3x = 180

x = 180 / 3

x = 60

Therefore, there are 60 trees in the garden.

To find the number of apple trees, we can substitute the value of x back into the equation:

(8/15) * 60 = 32

So, there are 32 apple trees in the garden.

To find the number of pear trees, we can also substitute the value of x back into the equation:

(4/15) * 60 = 16

So, there are 16 pear trees in the garden.

Answer

The total number of trees in the garden is 60. There are 32 apple trees and 16 pear trees.
