Question

В саду посажены рядами 600 яблонь и 400 груш. В каждом ряду число деревьев одинаково. При этом рядов с яблоними на 5 больше, чем рядов с грушами.Сколько в саду рядов яблонь и груш?

Answer 1

Так как число деревьев в каждом ряду одинаково то находим количество деревьев в 5 рядах        600-400=200
А в одном ряду    200/5=40 деревьев 
Теперь находим количество рядов
600/40=15 рядов яблонь
400/40=10 рядов груш

Answer 2

1)600-400=200
2)200:5=40(деревьев)в ряду
3)600:40=15(рядов яблонь)
4)400:40=10(рядов груш)
Ответ:10 рядов груш и 15 рядов яблонь :)

Answer 3

Problem Analysis

We are given that there are 600 apple trees and 400 pear trees planted in rows in a garden. The number of trees in each row is the same, and there are 5 more rows of apple trees than pear trees. We need to determine the number of rows of apple trees and pear trees in the garden.

Solution

Let's assume the number of rows of pear trees is x. Since there are 5 more rows of apple trees than pear trees, the number of rows of apple trees can be expressed as x + 5.

The total number of rows in the garden is the sum of the rows of apple trees and pear trees, which is (x + 5) + x = 2x + 5.

We are given that there are 600 apple trees and 400 pear trees in total. The number of trees in each row is the same, so we can calculate the number of trees in each row by dividing the total number of trees by the total number of rows.

Let's calculate the number of trees in each row:

- For apple trees: 600 / (2x + 5) - For pear trees: 400 / x

Since the number of trees in each row is the same, we can set up the following equation:

600 / (2x + 5) = 400 / x

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

Equation Solving

To solve the equation 600 / (2x + 5) = 400 / x, we can cross-multiply:

600x = 400(2x + 5)

Simplifying further:

600x = 800x + 2000

Bringing like terms to one side:

800x - 600x = 2000

200x = 2000

Dividing both sides by 200:

x = 10

Answer

Therefore, there are 10 rows of pear trees and 10 + 5 = 15 rows of apple trees in the garden.
