From 10 liters of milk, 2 kilograms of butter is obtained. How much milk do you need to take to get 12 kilograms of butter?

To solve this problem, the first step is to find out how many times less butter is obtained than milk. To do this, a given amount of milk must be divided by the butter obtained from this milk.

1) 10/2 = 5.

To find out how much milk you need to take to get 12 kilograms of butter, you need to multiply this amount of butter by 5. Because we learned that butter is obtained 5 times less than there was milk.

2) 12 * 5 = 60 liters.

Answer: to get 12 kilograms of butter, you need to take 60 liters of milk.
