Kendra is making bread, but the recipe she's using makes 4 loaves. She only wants to make one loaf. The changed recipe calls for 2 1/2 cups of flour and sugar combined. If the original recipe calls for 2 cups of sugar, find the amount of flour (in cups) in the original recipe
Since the original recipe makes 4 loaves, and Kendra only wants to make one loaf, she needs to divide all the ingredients by 4.
The recipe calls for 2 cups of sugar. When divided by 4, the amount of sugar needed for one loaf is 2/4 = 1/2 cup.
Since the changed recipe calls for 2 1/2 cups of flour and sugar combined, and Kendra wants to make one loaf, the amount of flour and sugar combined needed for one loaf is 2 1/2/4 = 1/2 cup.
Therefore, the amount of flour in the original recipe is 1/2 - 1/2 = 0 cups. Answer: \boxed{0}.
