Question

В саду растут яблони,груши и сливы .Яблони составляют 8/15 всех деревьев ,груши 4/15 всех деревьев ,а число слив равно 12 . Сколько всего деревьев в саду ?Сколько в нём яблонь и груш ?

Answer 1

12+8/15x+4/15x=x
12/15x+12=x
12:3/15=60 деревьев всего

яблони - 60:15*8=32      груши - 60:15*4=16  сливы - 12

Answer 2

Calculation of Total Trees in the Garden

To calculate the total number of trees in the garden, we need to determine the number of apple trees, pear trees, and plum trees.

Let's assume the total number of trees in the garden is represented by the variable T.

According to the given information: - Apple trees make up 8/15 of all the trees. - Pear trees make up 4/15 of all the trees. - The number of plum trees is equal to 12.

To find the total number of trees (T), we can set up the following equation:

8/15T + 4/15T + 12 = T

To solve this equation, we can multiply through by 15 to eliminate the fractions:

8T + 4T + 180 = 15T

Combining like terms:

12T + 180 = 15T

Subtracting 12T from both sides:

180 = 3T

Dividing both sides by 3:

T = 60

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

Calculation of Apple Trees and Pear Trees

To calculate the number of apple trees and pear trees in the garden, we can use the ratios provided.

According to the given information: - Apple trees make up 8/15 of all the trees. - Pear trees make up 4/15 of all the trees.

Using the total number of trees (T) calculated earlier as 60, we can find the number of apple trees and pear trees.

Number of apple trees: 8/15 * 60 = 32

Number of pear trees: 4/15 * 60 = 16

Therefore, there are 32 apple trees and 16 pear trees in the garden.

In summary, the total number of trees in the garden is 60, with 32 apple trees and 16 pear trees.
