Answer: 1.5
Step-by-step explanation: Reverse the equation to get the answer.
-13 divided by 2 is -6.5
add 8 and you'll get 1.5
You add each step from +5 to +10 to get 55
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.
