Question

12 рабочих сделали работу за 9 дней. За сколько дней сделали бы ту же работу 4 рабочих, если бы они работали с такой же производительностью?

Answer 1

1) 12:4=3 во столько раз меньше
2) 9*3=27 дн

Answer 2

Calculation of Work Days

To calculate the number of days it would take for 4 workers to complete the same job that 12 workers completed in 9 days, we can use the formula:

\[ \text{Work days} = \frac{\text{Number of workers} \times \text{Days}}{\text{Number of workers completing the job}} \]

Plugging in the given values: \[ \text{Work days} = \frac{12 \times 9}{4} \]

\[ \text{Work days} = 27 \]

So, it would take 4 workers 27 days to complete the same job.
