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 Orginal recipe

If the original recipe calls for 2 cups of sugar, then the combined amount of flour and sugar in the original recipe is 2 + 2 = <<2+2=4>>4 cups.

Since the original recipe makes 4 loaves, then the amount of combined flour and sugar for one loaf is 4/4 = <<4/4=1>>1 cup.
But the changed recipe calls for 2 1/2 cups of flour and sugar combined, meaning there is 2 1/2 - 1 = <<2+1/2-1=1.5>>1.5 cups of flour. Answer: \boxed{1.5}.
