1%2F3 of the 2-cup mixture is exactly 2%2F3 cup of floor.      <<<---=== A 2-cup mixture consists of 1/3 flour and 2/3 cornmeal.


After adding 1 cup of floor we have 12%2F3 = 5%2F3 cup of floor.


Now, the ratio  %285%2F3%29 : 3 = 5%2F9 = 0.5555 = 55.55%.


Answer.   Approximately what percent of the 3-cup mixture is flour?  -   55.55%.   Approximately.
