Question 532453
4 parts water and 1 part vinegar. I think of this as 5 parts, where 4/5 is water and 1/5 is vinegar.

For 3 cups, you would need 4/5 of the 3 cups to be water, so {{{(4/5)*3}}} which will give you {{{12/5}}} cups, or {{{2}}}{{{2/5}}} cups of water.

You would need 1/5 of the 3 cups to be vinegar, so {{{(1/5)*3}}} which will give you {{{3/5}}} cups of vinegar.
