Question

Две тракторные бригады вспахали вместе 762 га поля.Первая бригада работала 8 дней и вспахивала за день 48 га.Сколько гектаров поля вспахивала за день вторая бригада,если она работала 9 дней?Какая бригада вспахала больше и на сколько?

Answer 1

1) 8*48=384га- вспахала первая бригада; 2) 762-384= 378га- вспахала вторая бригада; 3) 378/9= 42га- вспахивала в день вторая бригада; 4)384-378= 6г- разность; Ответ : вторая бригада вспахивала за день 42га, и вспахала на 6 Га меньше первой бригады.

Answer 2

8*48=384 га за 8 дней 1 бригада

762-384=378 га за 9 дней вспахала 2 бригада

 378/9=42 га за день 2 бригада

 

384-378=6 га 1 бригада больше 2 бригады

 

 

 

 

Answer 3

Problem Analysis

We are given that two tractor brigades plowed a field together, covering a total area of 762 hectares. The first brigade worked for 8 days and plowed 48 hectares per day. We need to determine how many hectares the second brigade plowed per day if they worked for 9 days. Additionally, we need to determine which brigade plowed more and by how much.

Solution

To find out how many hectares the second brigade plowed per day, we can set up a proportion using the information given:

48 hectares / 8 days = x hectares / 9 days

We can solve this proportion to find the value of x, which represents the number of hectares the second brigade plowed per day.

To determine which brigade plowed more, we can compare the total area plowed by each brigade. If the second brigade plowed more, we will calculate the difference in hectares between the two brigades.

Let's calculate the values step by step.

Calculation

To find the number of hectares the second brigade plowed per day, we can solve the proportion:

48 hectares / 8 days = x hectares / 9 days

Cross-multiplying, we get:

48 hectares * 9 days = 8 days * x hectares

Simplifying, we have:

432 hectares = 8x hectares

Dividing both sides by 8, we find:

x hectares = 54 hectares

Therefore, the second brigade plowed 54 hectares per day.

To determine which brigade plowed more, we compare the total area plowed by each brigade. The first brigade plowed 48 hectares per day for 8 days, resulting in a total of 48 hectares/day * 8 days = 384 hectares.

The second brigade plowed 54 hectares per day for 9 days, resulting in a total of 54 hectares/day * 9 days = 486 hectares.

Therefore, the second brigade plowed more, covering an additional 486 hectares - 384 hectares = 102 hectares compared to the first brigade.

Answer

The second brigade plowed 54 hectares per day. The second brigade plowed more than the first brigade by 102 hectares.
