Question

. Для приготовления теста берут 4 части муки, 2 части молока и 1 часть сметаны. Сколько граммов молока надо взять, чтобы приготовить 2 кг 100 г теста? С обьяснением .

Answer 1

2 кг 100 г=2100
1) 4+2+1=7 (ч) - всего
2) 2100:7*2=300*2=600 (г)
Ответ: 600 граммов молока надо взять

Answer 2

Calculating the Amount of Milk Needed for the Dough

To calculate the amount of milk needed to prepare 2 kg 100 g of dough using the given ratio of ingredients (4 parts flour, 2 parts milk, and 1 part sour cream), we can use the following steps:

1. Determine the Total Parts of Ingredients: - The total parts of ingredients in the given ratio are 4 (flour) + 2 (milk) + 1 (sour cream) = 7 parts.

2. Calculate the Proportion of Milk: - To find the proportion of milk needed for the dough, we divide the weight of the dough by the total parts of ingredients and then multiply by the number of parts of milk.

3. Calculating the Amount of Milk: - Using the given ratio, the amount of milk needed for the dough can be calculated as follows:

   Milk needed = (Weight of dough / Total parts of ingredients) * Parts of milk
   

Substituting the given values: ``` Milk needed = (2100 g / 7) * 2 ```

Solving the equation: ``` Milk needed = (300 g) * 2 = 600 g ```

Therefore, 600 grams of milk are needed to prepare 2 kg 100 g of dough using the given ratio of ingredients.

Explanation

The given ratio of ingredients for the dough is 4 parts flour, 2 parts milk, and 1 part sour cream. This means that for every 4 parts of flour, 2 parts of milk and 1 part of sour cream are used. To calculate the amount of milk needed to prepare a specific weight of dough, we use the ratio to determine the proportion of milk required based on the total weight of the dough. In this case, for 2 kg 100 g of dough, the calculation shows that 600 grams of milk are needed to maintain the given ratio of ingredients.
