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?*
3 parts water clean:water=1:3 1:3=xcleaner:1gallon 1/3=xcleaner/1gallon times 3gallon both sides 1gallon=3xcleaner divide both sides by 3 1/3 gallon=xcleaner
