Question

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?*
1 ½ quarts 1 pint 2 quarts 1 quart

Answer 1

There are 4 quarts in a gallon and 8 pints in a gallon.  If you used 1 1/2 quarts of cleaner you would need 4 1/2 quarts of water.  1 1/2 + 1 1/2 + 1 1/2 = 4 1/2.  If you used 1 pint of cleaner it would take 3 pints of water.  If you take 2 quarts of cleaner it would take 6 quarts of water.  If you use 1 quart of cleaner it would take 3 quarts of water.  If you use 1 quart of window cleaner and 3 quarts of water.  The cleaning mix would be correct and fill a gallon jug.  So your answer is 1 quart.
