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?

You have a bucket 1 gallon big.To mix cleaner and water you need to divide the bucket's capacity into 4.It's easy in this case as gallon is divided into quarts (1 gallon is equal to 4 quarts).Since one part will be a window cleaner, it means that you will need to use 1 quart of the cleaner.
