Question

СРОЧНО!!! РЕШИТЕ ПОЖАЛУЙСТА ЗАДАЧУ ( по действиям)!!! Крестьянин выращивает овощи. На 60% всей его земли посажена капуста, а на одной третьей оставшейся земли растёт морковь. Сколько гектаров земли не занято ни под капусту, ни под морковь, если всего у крестьянина 12 гектаров земли?

Answer 1

Ответ:

3,2 га земли не занято

Пошаговое объяснение:

60% = 0,6

1. 12 * 0,6 = 7,2 (га) занимает капуста

2. 12 - 7,2 = 4,8 (га) оставшаяся земля

3. 4,8 * 1/3 = 48/10 * 1/3 = 48/30 = 1,6 (га) занимает морковь

4. 7,2 + 1,6 = 8,8 (га) занимают капуста и морковь

5. 12 - 8,8 = 3,2 (га) земли не занято

Answer 2

Problem Analysis

We are given that a peasant farmer is growing vegetables on his land. 60% of his land is planted with cabbage, and one-third of the remaining land is planted with carrots. We need to determine how many hectares of land are not occupied by either cabbage or carrots, given that the farmer has a total of 12 hectares of land.

Solution

To solve this problem, we need to calculate the area of land occupied by cabbage and carrots and subtract it from the total area of the farmer's land.

Let's calculate the area of land occupied by cabbage first. We know that 60% of the farmer's land is planted with cabbage. To find the area in hectares, we can multiply the total land area by 60% (0.6): ``` Area of land occupied by cabbage = 12 hectares * 0.6 = 7.2 hectares ```

Next, we need to calculate the area of land occupied by carrots. We know that one-third of the remaining land is planted with carrots. To find the remaining land area, we subtract the area occupied by cabbage from the total land area: ``` Remaining land area = 12 hectares - 7.2 hectares = 4.8 hectares ``` Now, we can calculate the area of land occupied by carrots by multiplying the remaining land area by one-third (0.33): ``` Area of land occupied by carrots = 4.8 hectares * 0.33 = 1.584 hectares ```

Finally, to find the area of land not occupied by either cabbage or carrots, we subtract the areas of land occupied by cabbage and carrots from the total land area: ``` Area of land not occupied = 12 hectares - 7.2 hectares - 1.584 hectares = 3.216 hectares ```

Therefore, the peasant farmer has 3.216 hectares of land that are not occupied by either cabbage or carrots.

Answer

The peasant farmer has 3.216 hectares of land that are not occupied by either cabbage or carrots.
