Eric's cake recipe calls for two and 1/2 lb of flour for everyone forth cup of sugar how many pounds of flour should use for one cup of sugar

To find out how many pounds of flour should be used for one cup of sugar in Eric's cake recipe, we need to determine the ratio between the flour and sugar.

According to the recipe, for every 1/4 cup of sugar, 2 and 1/2 lb of flour is required.

So, if we scale it down to just one cup of sugar, we divide 1 cup by 1/4 cup.

1 cup / (1/4 cup) = 4

Therefore, for one cup of sugar, Eric should use 4 times the amount of flour:

4 * 2 and 1/2 lb = 10 lb

Therefore, he should use 10 pounds of flour for one cup of sugar in his cake recipe.
