<PRE><B>Question 1043612</B>
a 2-cup mixture consists of 1/3 flour and 2/3 cornmeal. if 1 cup of flour is added to make a 3-cup mixture, approximately what percent of the 3-cup mixture is flour? 
------
# of cups:: 3 cups
# of cups of flour:: (1/3)(2) + 1 = 5/3 cup
----
Percent of flour = (5/3)/3 = 5/9 = 0.555.. = 55.6%
