A biscuit recipe calls for 2 pounds of all purpose flour and .75 pound of butter, what would be the baker’s percentage for butte
Goryan [66]

Answer: 37.5%


Explanation:


Percentage is defined as parts of an amount  in 100 parts of a basis. This must be stated mathamatically for better understanding and for calculations. It is the ratio:

             % = (parts / base) × 100.


In this case you need to express the amount of butter as a part in 100 parts of all purpose flour, which, using the above definition, is:


        % butter = (0.75 pounds of butter / 2 pound of flour) × 100

         % butter = 0.75 × 100 / 2 = 75 / 2 = 37.5


The answer is expressed as 37.5%.
