Question

Тракторная бригада вспахала 520 га.В первый день она вспахала 24% поля, во второй день 20% поля.Сколько гектар вспахала бригада в третий день?

Answer 1

1) 520*0,24=124,8 (вспахали в 1 день) 2) 520*0,2=104 (вспахали во 2 день) 3)520-(104+124,8)= сколько вспахали в 3 день

Answer 2

Calculating the Total Area Plowed by the Tractor Brigade

To calculate the total area plowed by the tractor brigade in the first two days and then determine the area plowed on the third day, we can follow these steps:

1. Calculate the Area Plowed on the First Day: - The tractor brigade plowed 24% of the total area on the first day. - To find the area plowed on the first day, we can use the formula: \[ \text{Area Plowed on the First Day} = \frac{24}{100} \times 520 \]

2. Calculate the Area Plowed on the Second Day: - The tractor brigade plowed 20% of the total area on the second day. - To find the area plowed on the second day, we can use the formula: \[ \text{Area Plowed on the Second Day} = \frac{20}{100} \times 520 \]

3. Calculate the Area Remaining for the Third Day: - To find the area remaining for the third day, we can subtract the areas plowed on the first two days from the total area: \[ \text{Area Remaining for the Third Day} = 520 - (\text{Area Plowed on the First Day} + \text{Area Plowed on the Second Day}) \]

4. Calculate the Area Plowed on the Third Day: - The area plowed on the third day is the area remaining after the first two days.

Let's calculate the area plowed on the first two days and then determine the area plowed on the third day.

Calculation

1. Area Plowed on the First Day: - \[ \text{Area Plowed on the First Day} = \frac{24}{100} \times 520 = 124.8 \, \text{hectares} \]

2. Area Plowed on the Second Day: - \[ \text{Area Plowed on the Second Day} = \frac{20}{100} \times 520 = 104 \, \text{hectares} \]

3. Area Remaining for the Third Day: - \[ \text{Area Remaining for the Third Day} = 520 - (124.8 + 104) = 291.2 \, \text{hectares} \]

4. Area Plowed on the Third Day: - The tractor brigade plowed 291.2 hectares on the third day.

Therefore, the tractor brigade plowed 291.2 hectares on the third day.
