Hi,
I addlbs flower in a baking pan and lbs sugar to bake a cake. We found out later that we need to add lbs more flower to make our cake. How much flower and sugar we will need to make cakes.
4 11/12 + 4 3/12 = 8 14/12 or 9 1/6 cups of flour need for one cake.
or 18 1/3 lbs flour for two cakes
or 4 1/4 lb of sugar for 2 cakes
