From 40 kg of milk, 8 kg of cream can be obtained. How many kilograms of cream will you get if you take milk 1) 4 times less 2) 2 times more. How many kilograms of milk will make 1 kg of cream?

1) If you take 4 times less milk, then the cream, respectively, will be 4 times less, that is:

8: 4 = 2 (kg) – cream.

Answer: we get 2 kg of cream.

2) If we take 2 times more milk, then the cream will also become 2 times more:

8 * 2 = 16 (kg) – cream.

Answer: we get 16 kg of cream.

40 kg of milk = 8 kg of cream;

x kg of milk = 1 kg of cream.

40: 8 = x: 1;

To find the average unknown term of the proportion, it is necessary to multiply the extreme terms and divide their product by the known average term.

x = 40 * 1: 8;

x = 5 (kg) – milk.
