Question

За три дня бригада вспахала 5480га пашни.за первый день было вспахано25 % от запланированного .за второй день 50% остатка.Сколько бригада вспахала за третий день

Answer 1

1 день - 25%
2 день - 50% остатка
3 день - ?

За первый день вспахали 5480*0,25=1370гп
За второй день вспахали (5480-1370)*0,5=2055га
За третий день
5480-(1370+2055)=5480-3425=2055га
Ответ:бригада вспахала за 3 день 2055га

Answer 2

5480:100=54,8
54,8*25=1370
1370:100=13,7
13,7*50=685
5480-(1370+685)=3425

Answer 3

Problem Analysis

We are given that a team plowed 5480 hectares of land in three days. On the first day, they plowed 25% of the planned area, and on the second day, they plowed 50% of the remaining area. We need to determine how much the team plowed on the third day.

Solution

To solve this problem, we can break it down into three steps:

1. Calculate the area plowed on the first day. 2. Calculate the remaining area after the first day. 3. Calculate the area plowed on the second day. 4. Calculate the remaining area after the second day. 5. Calculate the area plowed on the third day.

Let's calculate each step one by one.

Step 1: Calculate the area plowed on the first day

The team plowed 25% of the planned area on the first day. To find the area plowed on the first day, we can multiply the planned area by 25% (0.25).

Area plowed on the first day = 5480 * 0.25 = 1370 hectares.

Step 2: Calculate the remaining area after the first day

To find the remaining area after the first day, we subtract the area plowed on the first day from the total planned area.

Remaining area after the first day = Total planned area - Area plowed on the first day = 5480 - 1370 = 4110 hectares.

Step 3: Calculate the area plowed on the second day

The team plowed 50% of the remaining area on the second day. To find the area plowed on the second day, we can multiply the remaining area by 50% (0.5).

Area plowed on the second day = 4110 * 0.5 = 2055 hectares.

Step 4: Calculate the remaining area after the second day

To find the remaining area after the second day, we subtract the area plowed on the second day from the remaining area after the first day.

Remaining area after the second day = Remaining area after the first day - Area plowed on the second day = 4110 - 2055 = 2055 hectares.

Step 5: Calculate the area plowed on the third day

The area plowed on the third day is equal to the remaining area after the second day.

Area plowed on the third day = Remaining area after the second day = 2055 hectares.

Therefore, the team plowed 2055 hectares on the third day.
