Question

Две тракторные бригады вспахали вместе 762 га. Поля первая бригада работала 8 не испугалась 48 гектаров. Сколько гектаров в поле вспахала за 1 2 бригада я наблюдала 9 дней? Какая бригада вспахала больше и на сколько?

Answer 1

1) 8*48=384 (га)-вспахала 1-ая бригада.

2) 762-384=378 (га) -вспахала 2-ая бригада.

3) 378/9=42 (га)-вспахивает 2 бригада за день .

Итог: Первая бригада вспахала больше.

384-378=6 га

Ответ: 1-ая бригада вспахала больше, на 6 га

Answer 2

Calculation of the Total Area Plowed by Two Tractor Brigades

To calculate the total area plowed by the two tractor brigades, we need to add the areas plowed by each brigade.

The first brigade plowed 48 hectares, and the second brigade plowed an unknown area. The total area plowed by both brigades is 762 hectares.

Let's denote the area plowed by the second brigade as x hectares.

Therefore, the equation representing the total area plowed is:

48 hectares + x hectares = 762 hectares

To find the value of x, we can subtract 48 hectares from both sides of the equation:

x hectares = 762 hectares - 48 hectares

Simplifying the equation:

x hectares = 714 hectares

So, the second brigade plowed 714 hectares.

Calculation of the Number of Days Observed

The question states that the observer watched the two brigades for 9 days.

Determining which Brigade Plowed More and by How Much

To determine which brigade plowed more, we need to compare the areas plowed by each brigade.

The first brigade plowed 48 hectares, and the second brigade plowed 714 hectares.

Comparing the areas, we can see that the second brigade plowed more.

The second brigade plowed 666 hectares more than the first brigade.

Therefore, the second brigade plowed more by 666 hectares.
