Question

в первый день бригада вспахала три восьмых участка. во второй день 40 процентов остатка, а в третий день остальные 216 га. найдите площадь участка.

Answer 1

І - 3/8

ІІ - 40% остатка      } ?га

ІІІ - 216га

 

1 - 3/8=5/8 - вспахали всего во ІІ и ІІІ день (остаток)

100%- остаток

100%-40%=60% - остатка составляют 216га

 

60%-216га

100% - ?га

216:60*100=360(га) - 5/8 поля

360*8/5=576(га) - площадь участка 

 

Answer 2

Calculating the Area of the Plot

To find the area of the plot, we can use the information provided about the work done by the brigade over three days.

1. Work Done on Each Day: - On the first day, the brigade plowed three eighths of the plot. - On the second day, they plowed 40% of the remaining plot. - On the third day, they plowed the remaining 216 hectares.

2. Calculating the Area: - We can calculate the area of the plot using the work done by the brigade over the three days.

- First, we calculate the area plowed on the first day, then the area plowed on the second day, and finally the area plowed on the third day.

3. Calculation Steps: - Let's calculate the area plowed on each day step by step.

- Day 1: - The brigade plowed three eighths of the plot. - This can be calculated as 3/8 of the total area.

- Day 2: - The brigade plowed 40% of the remaining plot. - We can calculate the remaining area after the first day and then find 40% of that area.

- Day 3: - The remaining 216 hectares were plowed on the third day.

4. Calculation: - Let's perform the calculations step by step to find the total area of the plot.

- Day 1: - Area plowed on the first day = 3/8 of the total area.

- Day 2: - Remaining area after the first day = Total area - Area plowed on the first day. - Area plowed on the second day = 40% of the remaining area after the first day.

- Day 3: - Remaining area after the second day = Remaining area after the first day - Area plowed on the second day. - Area plowed on the third day = Remaining area after the second day, which is 216 hectares.

5. Final Calculation: - We can add up the areas plowed on each day to find the total area of the plot.

- Total Area: - Total area = Area plowed on the first day + Area plowed on the second day + Area plowed on the third day.

- Let's perform the calculations to find the total area of the plot.
