1 gallon makes 128 ounces and 1 ounce is 0.0078 gallon in U.S measure. There are 8 ounces in a cup, 2 cups in a pint, 2 pints in a quart and 4 quarts in a gallon. That makes 128 ounces in a gallon US. In UK 20 ounces to the pint, 8 pints to the gallon which makes 160 ounces Imperial measure.
1 Fluid Oz.= 0.0078125 Gallons
1 Gallon= 128 Fluid Oz.
In US, fluid 128 ounces or 16 cups are in 1 US gallon, but in UK, 1 fluid gallon equals 160 fluid ounces. "US fluid ounce is about 4 percent larger than UK fluid ounce"
1 gallon = 128 fluid ounces.

128 oz.
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.
