Question

В питомнике вырастили 25 700 саженцев деревьев;саженцев яблонь-8 580,что на 4 210 меньше ,чем саженцев вишен; остальные -саженцы слив.Сколько саженцев слив было выращено в питомнике? Реши задачу разными способами.

Answer 1

Способ 1: 1) 8580+4210=12790 - вишня 2) 8580+12790=21370 - яблони и вишня 3) 25700-21370=4330 сливы
Способ 2: 25700-((8580+4210)+8580

Answer 2

Problem Analysis

In the nursery, a total of 25,700 tree seedlings were grown. Of these, 8,580 were apple seedlings, which is 4,210 fewer than the number of cherry seedlings. The remaining seedlings were plum seedlings. We need to determine how many plum seedlings were grown in the nursery.

Solution 1: Using Subtraction

We can solve this problem by subtracting the number of apple seedlings from the total number of seedlings to find the number of plum seedlings.

Let's calculate it step by step:

1. Total number of seedlings = 25,700 2. Number of apple seedlings = 8,580 3. Number of cherry seedlings = Number of apple seedlings + 4,210 = 8,580 + 4,210 = 12,790 4. Number of plum seedlings = Total number of seedlings - Number of apple seedlings - Number of cherry seedlings = 25,700 - 8,580 - 12,790 = 4,330

Therefore, there were 4,330 plum seedlings grown in the nursery.

Solution 2: Using Addition

We can also solve this problem by adding the number of apple seedlings and the difference between the number of apple seedlings and cherry seedlings to find the number of plum seedlings.

Let's calculate it step by step:

1. Number of apple seedlings = 8,580 2. Difference between the number of apple seedlings and cherry seedlings = 4,210 3. Number of cherry seedlings = Number of apple seedlings + Difference between the number of apple seedlings and cherry seedlings = 8,580 + 4,210 = 12,790 4. Total number of seedlings = Number of apple seedlings + Number of cherry seedlings + Number of plum seedlings = 8,580 + 12,790 + Number of plum seedlings = 25,700 5. Number of plum seedlings = Total number of seedlings - Number of apple seedlings - Number of cherry seedlings = 25,700 - 8,580 - 12,790 = 4,330

Therefore, there were 4,330 plum seedlings grown in the nursery.

Solution 3: Using Algebra

We can also solve this problem using algebraic equations.

Let's assume the number of plum seedlings is represented by the variable "P".

1. Total number of seedlings = 25,700 2. Number of apple seedlings = 8,580 3. Number of cherry seedlings = Number of apple seedlings + 4,210 = 8,580 + 4,210 = 12,790 4. Number of plum seedlings = Total number of seedlings - Number of apple seedlings - Number of cherry seedlings P = 25,700 - 8,580 - 12,790 P = 4,330

Therefore, there were 4,330 plum seedlings grown in the nursery.

Summary

In the nursery, a total of 25,700 tree seedlings were grown. Of these, 8,580 were apple seedlings, which is 4,210 fewer than the number of cherry seedlings. The remaining seedlings were plum seedlings, and there were 4,330 plum seedlings grown in the nursery.
