The total ratio is 2 + 1 = 3.
The fraction of brown flour is 1/3 because 1/3 of the total flour is brown.
Alternatively, we can find the fraction of white flour and then subtract it from 1 to find the fraction of brown flour:
The fraction of white flour is 2/3 because there are 2 parts white flour for every 3 parts total flour.
Therefore, the fraction of brown flour is 1 - 2/3 = 1/3.
