AI explanation

The total volume of the mixture is 30 litres, and the components of milk and water are in a 7 to 3 ratio, meaning there are 10 total parts. To find the volume of water, divide the total volume by the number of parts to determine that one part equals 30 divided by 10, which is 3 litres. Multiplying this volume by the 3 parts representing water gives a total water volume of 9 litres.
