Question

За 4 год Вадим прополов b грядок, а Денис тільки c . C c грядок.У скільки разів продуктивність більша від продуктивності Дениса.

Answer 1

За 1 годину Вадим прополов $\frac{b}{4}$ грядок (це його продуктивність), а Денис  $\frac{c}{4}$ (це його продуктивність).
Щоб дізнатися у скільки разів продуктивність Вадима більша, потрібно 
$\frac{b}{4}$ :  $\frac{c}{4}$ =$\frac{b}{4} \frac{4}{c} = \frac{b}{c}$
Відповідь: у $\frac{b}{c}$   разів більша

Answer 2

Productivity Comparison Between Vadim and Denis

Vadim has been working in the garden for 4 years, while Denis has only been working for 1 year. We need to compare the productivity of Vadim and Denis to determine how many times Vadim's productivity is greater than Denis's.

To calculate this, we can use the formula:

Productivity = Output / Input

Where Output is the amount of produce harvested and Input is the time spent working in the garden.

Let's assume that Vadim's productivity is represented by V and Denis's productivity is represented by D.

Given: - Vadim's time spent working = 4 years - Denis's time spent working = 1 year

We can calculate the productivity ratio as follows:

V / D = (Output_Vadim / Input_Vadim) / (Output_Denis / Input_Denis)

Since we don't have specific output and input values, we can't calculate the exact productivity ratio. However, we can make a general comparison based on the time spent working.

Conclusion

Based on the information provided, Vadim's productivity is expected to be significantly higher than Denis's, given that Vadim has been working in the garden for 4 years compared to Denis's 1 year.
