1 gallon = 128 fluid ounces
1,792 fl oz = (1,792 / 128) = 14 gallons
4 gal = 512 fl oz
(6 oz per 100 gal) times (20) = (120 oz per 100 gal), or (1.2 oz per gal) .
128 oz
1 US gal is 128 fluid ounces, so 2 gal is 256 fl oz.
That is 256 fl oz.
That is 192 fl oz.
That is 192 fl oz.
That is 64 fl oz.
That is 384 fl oz.
Start by simplifying the problem. 8 oz to 50 gal is the same as 4 oz to 25 gal. Divide 4 by 25 and you get .16 ounces to one gallon.
