Question

В трех тарелках было 127 вишен Когда с первой тарелки сьели 21 вишню, со второй 9, а с третьей третью часть того ,что с первой, во всех тарелках вишен стало поровну. сколько вишен было на каждой тарелке сначала? 2) Измени вопрос задачит так, чтобы ее решение стало короче на два действия?. Мне нужно решение второго действия .

Answer 1

1. 21/3=7 вишен съели с 3 тарелки
2. 127-21-9-7=90 вишен осталось
3. 90/3=30 вишен стало на каждой тарелке поровну
4. 30+21=41 вишня была на 1 тарелке
5. 30+9=39 вишен было на 2 тарелке
6. 30+7=37 вишен было на 3 тарелке
вопрос: сколько вишен было изначально на 1 тарелке?
решение: первые четыре действия

Answer 2

Problem Statement

В трех тарелках было 127 вишен. Когда с первой тарелки съели 21 вишню, со второй 9, а с третьей третью часть того, что с первой, во всех тарелках вишен стало поровну. Сколько вишен было на каждой тарелке сначала?

Solution

Let's solve the problem step by step:

Step 1: Let's assume the number of cherries in the first plate is x.

Step 2: According to the problem, when 21 cherries were eaten from the first plate, the remaining cherries in the first plate would be x - 21.

Step 3: Similarly, when 9 cherries were eaten from the second plate, the remaining cherries in the second plate would be x - 9.

Step 4: Finally, when one-third of the cherries from the first plate were added to the third plate, the number of cherries in the third plate would be (x - 21) / 3.

Step 5: According to the problem, the number of cherries in all three plates should be equal. So, we can set up the following equation:

x + (x - 21) + (x - 9) = (x - 21) / 3

Step 6: Now, let's solve the equation to find the value of x.

3x + 3(x - 21) + 3(x - 9) = x - 21

3x + 3x - 63 + 3x - 27 = x - 21

9x - 90 = x - 21

8x = 69

x = 8.625

Since we cannot have a fraction of cherries, we need to round the value of x to the nearest whole number.

Therefore, there were approximately 9 cherries in the first plate initially.

Now, let's move on to the second part of your question.

Revised Problem Statement

Измените вопрос задачи так, чтобы ее решение стало короче на два действия. Мне нужно решение второго действия.

Revised Solution - Second Action

To make the solution shorter by two steps, we can simplify the problem by removing the step where we calculate the number of cherries in the third plate.

Revised problem statement: В трех тарелках было 127 вишен. Когда с первой тарелки съели 21 вишню, а со второй 9, во всех тарелках вишен стало поровну. Сколько вишен было на каждой тарелке сначала?

Revised solution:

Step 1: Let's assume the number of cherries in the first plate is x.

Step 2: According to the problem, when 21 cherries were eaten from the first plate, the remaining cherries in the first plate would be x - 21.

Step 3: Similarly, when 9 cherries were eaten from the second plate, the remaining cherries in the second plate would be x - 9.

Step 4: According to the problem, the number of cherries in all three plates should be equal. So, we can set up the following equation:

x + (x - 21) + (x - 9) = 127

Step 5: Now, let's solve the equation to find the value of x.

3x - 30 = 127

3x = 157

x = 52.333

Since we cannot have a fraction of cherries, we need to round the value of x to the nearest whole number.

Therefore, there were approximately 52 cherries in the first plate initially.
