Question

Марат выполнил работу за 12 дней.Самат выполнил ту же работу за36 дней.за сколько дней они выполнят эту работу вместе?

Answer 1

1:12=1/12 часть раб за 1 день марат
1:36=1/36 часть раб за 1 д сам
1/12+1/36=4/36=1/9 часть раб за 1 д вместе
1:1/9=9 дней

Answer 2

Calculation of Work Efficiency

To determine how long it would take Marat and Samat to complete the work together, we need to calculate their individual work efficiencies. Work efficiency is measured by the amount of work completed per unit of time.

Let's denote the amount of work as W and the time taken by Marat as T1 (12 days) and by Samat as T2 (36 days).

Marat's work efficiency can be calculated as W / T1 and Samat's work efficiency as W / T2.

Calculation of Combined Work Efficiency

To find out how long it would take them to complete the work together, we need to calculate their combined work efficiency. The combined work efficiency is the sum of their individual work efficiencies.

Let's denote the combined work efficiency as C.

The combined work efficiency can be calculated as 1 / (1/T1 + 1/T2).

Calculation of Time Taken to Complete the Work Together

To calculate the time taken to complete the work together, we need to divide the total amount of work by the combined work efficiency.

Let's denote the time taken to complete the work together as T.

The time taken to complete the work together can be calculated as W / C.

Calculation

Given that Marat completed the work in 12 days (T1 = 12) and Samat completed the same work in 36 days (T2 = 36), we can calculate the time taken to complete the work together.

Using the formulas mentioned above, we can calculate the combined work efficiency and the time taken to complete the work together.

Marat's work efficiency: W / T1 = 1 / 12

Samat's work efficiency: W / T2 = 1 / 36

Combined work efficiency: C = 1 / (1/T1 + 1/T2)

Time taken to complete the work together: T = W / C

Unfortunately, the specific values for the amount of work (W) are not provided in the question. Therefore, we cannot calculate the exact time it would take Marat and Samat to complete the work together without this information.

If you have the value for the amount of work, please provide it so that we can calculate the answer accurately.
