Question

Я задумал число.четверть этого числа поделил пополам.а полученное число утроил.увеличив результат на 2.я получил 8.какое число я задумал?

Answer 1

Считаем в обратном порядке, выполняя противоположные действия. (8-2):3*2*4=16

Answer 2

Solution:

To solve this problem, we can follow the steps provided and work backward to find the original number.

1. Start with 8 and work backward: - We know that after performing the operations, the result is 8.

2. Reverse the operations: - We need to work backward from 8 to find the original number.

3. Undo the last operation: - The last operation was to increase the result by 2. So, we subtract 2 from 8 to get 6.

4. Undo the previous operation: - Before that, the result was tripled. So, we need to divide 6 by 3 to get 2.

5. Undo the next operation: - Before that, the result was halved. So, we need to multiply 2 by 2 to get 4.

6. Undo the initial operation: - Before that, a quarter of the number was taken. So, we need to multiply 4 by 4 to get the original number.

Conclusion:

The original number that was initially thought of is 16.
