Question

Молоко даёт 25%сливок,сливки дают 20% масла.Сколько масла получится из молока надоенного за 15 дней от 360 коров,если каждая корова в среднем даёт 15 кг молока в день.

Answer 1

сколько всего молока

(360*15)*15=81000кг

сколько получится сливок из этого молока

81000:100*25=20250 кг

сколько получится масла из этих сливок

20250:100*20=4050 кг

 

Answer 2

Calculating the Amount of Butter from Milk

To calculate the amount of butter obtained from the milk produced by 360 cows over 15 days, we can follow these steps:

1. Calculate the Total Milk Produced: - Each cow produces 15 kg of milk per day. - Total milk produced by 360 cows in 15 days = 360 cows * 15 kg/cow/day * 15 days.

2. Calculate the Cream Content: - Given that milk gives 25% cream, we can calculate the amount of cream obtained from the total milk produced.

3. Calculate the Butter Content: - Given that cream gives 20% butter, we can calculate the amount of butter obtained from the cream.

Let's calculate each step.

Step 1: Calculate the Total Milk Produced

The total milk produced by 360 cows in 15 days: ``` 360 cows * 15 kg/cow/day * 15 days = Total milk produced ```

Step 2: Calculate the Cream Content

The amount of cream obtained from the total milk produced: ``` Total milk produced * 25% = Amount of cream ```

Step 3: Calculate the Butter Content

The amount of butter obtained from the cream: ``` Amount of cream * 20% = Amount of butter ```

Let's calculate the total amount of butter obtained from the milk produced by 360 cows over 15 days.

Calculation

1. Total Milk Produced: - Total milk produced = 360 cows * 15 kg/cow/day * 15 days - Total milk produced = 360 * 15 * 15 = 81,000 kg

2. Cream Content: - Amount of cream = Total milk produced * 25% - Amount of cream = 81,000 kg * 25% = 20,250 kg

3. Butter Content: - Amount of butter = Amount of cream * 20% - Amount of butter = 20,250 kg * 20% = 4,050 kg

Answer:

The amount of butter obtained from the milk produced by 360 cows over 15 days is 4,050 kilograms.
