Question

Тракторная бригада в первый день вспахала 7/30 всего участка, во второй день 0,4 всего участка, а в третий день - остальные 220 га. Найдите площадь всего участка.

Answer 1

0.4=12/30
7/30+12/30=19/30 вспахали в первые два дня
11/30 в третий день 11/30=220га
220:11/30=15га вспахивают в день
30*15=450га весь участок

Answer 2

Calculation of Total Area

To find the total area of the plot, we need to add up the areas plowed on each day.

On the first day, the tractor brigade plowed 7/30 of the total area. On the second day, they plowed 0.4 of the total area. And on the third day, they plowed the remaining 220 hectares.

To calculate the total area, we can add up the areas plowed on each day:

Total Area = Area plowed on Day 1 + Area plowed on Day 2 + Area plowed on Day 3

Let's calculate the total area step by step:

1. Area plowed on Day 1: 7/30 of the total area. 2. Area plowed on Day 2: 0.4 of the total area. 3. Area plowed on Day 3: 220 hectares.

Now, let's calculate the total area:

1. Area plowed on Day 1: 7/30 of the total area. 2. Area plowed on Day 2: 0.4 of the total area. 3. Area plowed on Day 3: 220 hectares.

To find the total area, we need to add up these three areas:

Total Area = (7/30) * Total Area + (0.4) * Total Area + 220

We can solve this equation to find the value of the total area.

Unfortunately, the given information does not provide enough data to calculate the total area of the plot. The equation is incomplete, as we don't have the value of the total area to solve for it.
