Calculating Cream from Milk

To calculate the amount of cream obtained from 15 kg of milk, we can use the given ratio of 75 kg of milk producing 12 kg 500 g of cream.

Step 1: Calculate the Ratio First, let's calculate the ratio of milk to cream: - 75 kg of milk produces 12 kg 500 g of cream.

Step 2: Use the Ratio to Calculate Now, we can use this ratio to find out how much cream can be obtained from 15 kg of milk.

Using the given ratio, we can set up a proportion to find the amount of cream obtained from 15 kg of milk: - 75 kg of milk is to 12 kg 500 g of cream as 15 kg of milk is to x kg of cream.

Let's solve for x: - (75 kg / 12 kg 500 g) = (15 kg / x kg)

By cross-multiplication, we get: - 75 kg * x kg = 12 kg 500 g * 15 kg

Solving for x, we find: - x = (12 kg 500 g * 15 kg) / 75 kg

Let's calculate the value of x: - x = (12.5 kg * 15) / 75 = 2.5 kg

Answer: So, from 15 kg of milk, 2.5 kg of cream can be obtained.

Amount of Milk Needed for 20 kg of Cream

To find out how much milk is needed to produce 20 kg of cream, we can use the given ratio of 75 kg of milk producing 12 kg 500 g of cream.

Using the given ratio, we can set up a proportion to find the amount of milk needed to produce 20 kg of cream: - 75 kg of milk is to 12 kg 500 g of cream as x kg of milk is to 20 kg of cream.

Let's solve for x: - (75 kg / 12 kg 500 g) = (x kg / 20 kg)

By cross-multiplication, we get: - 75 kg * 20 kg = 12 kg 500 g * x kg

Solving for x, we find: - x = (12 kg 500 g * 20 kg) / 75 kg

Let's calculate the value of x: - x = (12.5 kg * 20) / 75 = 3.33 kg

Answer: So, to produce 20 kg of cream, approximately 3.33 kg of milk is needed.
