Ley m be the percentage of milk, w be the percentage of water, n is the percentage we must remove.

m = 75
w = 25
n = 1 / 3

The whole 3 equations boil down to this:

Okay, I thought you just needed some fraction help but you are asking for a mixture problem. I will try and solve that.

That is right. Take 1 part of the milk ( there are 3 ) and replace it with water. You now have 2 parts milk and 2 parts water. It is 50:50 now.

But 1 part of the milk is only 1 / 4 of the 4 parts of the mixture. So we need to replace 1 part of the mixture which is 1 / 4 of the mixture.

yeah so milk is 3/4 part of it and water is 1/4 part
