Question 1210377
.
If you have to mix 1 gallon of water with 1/4 cup of mixing solution, 
how would you figure out how much you would need if you only use 1 quart of water.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~



One gallon is  4  quarts.


Or,  in other words,  one quart is  1/4  of a gallon.


So,  following to your recipe,  if you have  1/4  of a gallon of water,  you need to mix it


with   {{{(1/4)*(1/4)}}} = {{{1/16}}}   of a cup of mixing solution,  to keep the assigned proportion.
