The question was posed recently: can you identify a proportion merely by looking at it?
As was pointed out by astute readers, various lighting and staging issues added a degree of uncertainty to the problem, but even so, a plurality of people were able to correctly identify the ratio of white sugar to total sugar.
As the above sequences of images suggests, the mixture was created from one part white sugar and two parts dark sugar. This makes the proportion of white sugar equal to 1/3.
Stay tuned for the next visual proportion challenge!
