You are going to mix a gallon bucket of window cleaner. the instructions direct you to mix 1 part cleaner to 3 parts water. how much cleaning solution will you need to use?

Well,  . . 
Let's divide the gallon into 4 Quarts.

if 1 part cleaner need to be mixed every 3 parts of water, it's means  that you need about 1/4 gallon of cleaning solution

hope this helps
