Ou 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, which is 1 gallon big.

So, to mix cleaner and water, you have to divide the bucket's capacity into 4.

In this case, it's 1 quart of the cleaner, as 1 gallon is 4 quarts. 4 quarts / 4 quarts = 1 quart.

Have a very nice day : D
