Question

Засеяли 24% поля. Осталось засеять 45,6 га этого поля. Найдите площадь всего поля.

Answer 1

100%-24%=76%-осталось засеять после первого посева (в %)
76%-45,6
24%-x
Делаем пропорцией
76x=1094.4
x=1094.4/76
x=14.4 (24%)
100%=76%+24%
100%=14.4+45.6=60 га
Ответ:60 га

Answer 2

1) 100-24=76% осталось засеять

т.е. 45.6 га = 76% всего поля.

2) 45.6 : 0.76 = 60 га все поле

Ответ: S всего поля - 60 га

Answer 3

Calculation of the Total Area of the Field

To find the total area of the field, we need to determine the area that has already been seeded and subtract it from the remaining area that needs to be seeded.

Given: - 24% of the field has already been seeded. - There are 45.6 hectares (ha) remaining to be seeded.

To calculate the total area of the field, we can use the following formula:

Total Area = Seeded Area + Remaining Area

Let's calculate the total area step by step:

1. Calculate the area that has already been seeded: - Seeded Area = (24/100) * Total Area

2. Calculate the remaining area to be seeded: - Remaining Area = 45.6 ha

3. Substitute the values into the formula: - Total Area = Seeded Area + Remaining Area

Now, let's perform the calculations:

1. Calculate the area that has already been seeded: - Seeded Area = (24/100) * Total Area

2. Calculate the remaining area to be seeded: - Remaining Area = 45.6 ha

3. Substitute the values into the formula: - Total Area = Seeded Area + Remaining Area

Total Area = (24/100) * Total Area + 45.6 ha

To solve this equation, we can isolate the Total Area on one side:

Total Area - (24/100) * Total Area = 45.6 ha

Simplifying the equation:

Total Area * (1 - 24/100) = 45.6 ha

Total Area * (76/100) = 45.6 ha

Dividing both sides of the equation by (76/100):

Total Area = (45.6 ha) / (76/100)

Simplifying the right side of the equation:

Total Area = (45.6 ha) * (100/76)

Total Area ≈ 60 ha

Therefore, the total area of the field is approximately 60 hectares.
