Answer 1

(15/5)-(8/15)+(4/15)=(15/15)-(12/15)=3/15 часть слив от всех деревьев
(3/15)=12
(1/15)=4
(8/15)=8*4=32 количество яблонь
(4/15)=4*4=16 количество груш

Answer 2

Problem Analysis

To solve this problem, we need to determine the total number of trees in the garden and the number of apple and pear trees. We are given the following information: - Apple trees make up 8/15 of all the trees. - Pear trees make up 4/15 of all the trees. - There are exactly 12 plum trees in the garden.

Let's calculate the total number of trees and the number of apple and pear trees.

Solution

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

According to the given information: - Apple trees make up 8/15 of all the trees, so the number of apple trees is (8/15) * x. - Pear trees make up 4/15 of all the trees, so the number of pear trees is (4/15) * x. - There are exactly 12 plum trees in the garden.

To find the total number of trees, we can set up the following equation: (8/15) * x + (4/15) * x + 12 = x

Now, let's solve this equation to find the value of x.

(8/15) * x + (4/15) * x + 12 = x (12/15) * x + 12 = x 12/15 * x = x - 12 12x = 15x - 180 3x = 180 x = 60

Therefore, the total number of trees in the garden is 60.

To find the number of apple trees, we can substitute the value of x into the equation: Number of apple trees = (8/15) * 60 = 32

To find the number of pear trees, we can substitute the value of x into the equation: Number of pear trees = (4/15) * 60 = 16

Answer

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