Is there a graph or a picture to go along with it? it would be easier for me to answer :)
A quart has 32oz in it. If the solution needs 5% bleach then all you do is multiply 32*(5/100) or 32*.05. Either way, the answer is 1.6. So you need 1.6 oz to make a quart 5% bleach solution.
ayo we need to see the images so we can give you the right answer
