By what number will you multiply each ingredient in the original recipe to obtain the new ingredient amount?

To determine the number by which to multiply each ingredient in the original recipe, you need to divide the desired amount of each ingredient by the original amount. For example, if the original recipe calls for 2 cups of flour and you need 4 cups, you would multiply by 2 (4 ÷ 2 = 2). This factor will be consistent across all ingredients in the recipe to maintain the proportions.
