108÷9=12-9 рабочих

Answer 2

Task Analysis

To solve this problem, we can use the concept of "man-days" to calculate the total work done. The formula for man-days is:

Total work = Number of workers × Number of days

We can use this formula to find the total work done by 6 workers in 18 days and then calculate the number of days required for 9 workers to complete the same amount of work.

Calculation

Given: - 6 workers can complete the task in 18 days.

Using the formula: Total work = Number of workers × Number of days

We can calculate the total work done by 6 workers in 18 days.

Total Work Done by 6 Workers in 18 Days

Total work = 6 workers × 18 days Total work = 108 worker-days

Now, we need to find out how many days 9 workers will take to complete the same amount of work.

Days Required for 9 Workers to Complete the Same Work

Using the same formula: Total work = Number of workers × Number of days

We can calculate the number of days required for 9 workers to complete the same amount of work.

Given: - Total work = 108 worker-days - Number of workers = 9

Calculation

Number of days = Total work / Number of workers Number of days = 108 worker-days / 9 workers Number of days = 12 days

Answer

So, 9 workers will be able to complete the same work in 12 days.
