A recipe calls for 5 1/2 cups of flour. Molly only has 3 3/4 cups of flour. Write and solve an equation to find the additional amount of flour Molly needs to make the recipe.
Since the recipe calls for 5 1/2 cups of flower and Molly only has 3 3/4 cups, subtract 3 3/4 from 5 1/2 to get the remaining cups of flour needed to make the recipe.
