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?

If the changed recipe calls for 2 1/2 cups of flour and sugar combined, and the original recipe calls for 2 cups of sugar, the remaining amount is 2 1/2 - 2 = <<2.5-2=0.5>>0.5 cups of flour. Answer: \boxed{0.5}.
