1. a recipe calls for cups of flour, cup of white sugar, and cup of brown sugar. the recipe makes 6 servings.
(a) how many cups of flour are there per serving? show your work.
(b) how many total cups of sugar (white and brown) are there per serving? show your work.
(c) suppose you modify the recipe so that it makes 9 servings. how much more flour do you need for the modified recipe than you need for the original recipe? show your work

For (A) take 6÷ 1 1/2= 4 cups. There are 4 cups of flour per serving. For (B) add the total cups of white and brown sugar, then, divide that number by 6. There are 8 cups of white sugar per serving ( 6÷ 3/4=8 cups). And there are 18 cups of brown sugar per serving ( 6÷ 1/3= 18 cups). So, therefore there are 26 cups of white and Brown sugar per serving. For (C) take 9 divided by 1 1/2 cups of flour , to see how many cups per serving, then take 6 divide by 1 1/2= 4 cups.
So, 9÷1 1/2= 6 cups and 6÷ 1 1/2= 4 cups 6-4=2 cups . You would need two more cups of flour for the modified recipe than you would need for the original recipe.
