Question

Две сеялки марок A и B занимаются посевом ржи. Сеялка марки А засеяла некоторую площадь, затратив 864 зерна. Расход зерна при этом составил 54 кг на 1 га поля. Сколько килограммов зерна понадобится сеялке марки B, чтобы засеять такую же площадь, если она расходует 96 кг зерна на 1 га поля?

Answer 1

864:54=16га    16*96=1536кг=1т536кг

Answer 2

Problem Analysis

We are given two seeders, A and B, that are used for sowing rye. Seeder A sowed a certain area using 864 grains of seed, with a seed consumption rate of 54 kg per hectare. We need to determine how many kilograms of seed seeder B will need to sow the same area if it has a seed consumption rate of 96 kg per hectare.

Solution

To solve this problem, we can use the concept of proportionality. The amount of seed required by each seeder is directly proportional to the seed consumption rate. We can set up a proportion to find the amount of seed required by seeder B.

Let's assume x represents the amount of seed required by seeder B.

The proportion can be set up as follows:

54 kg / 1 ha = 864 grains / x ha

To solve for x, we can cross-multiply and solve for x:

54 kg * x ha = 864 grains * 1 ha

Simplifying the equation:

x = (864 grains * 1 ha) / 54 kg

Now, we can substitute the given values into the equation to find the value of x.

Calculation

Using the given values: - Seeder A: 864 grains, 54 kg/ha - Seeder B: x kg/ha

Substituting the values into the equation:

x = (864 grains * 1 ha) / 54 kg

Calculating the value of x:

x = (864 grains * 1 ha) / 54 kg = 16 ha

Therefore, seeder B will require 16 kg of seed to sow the same area.

Answer

Seeder B will require 16 kg of seed to sow the same area if it has a seed consumption rate of 96 kg per hectare.
