sleet_krkn [62]

Answer:

Cups of flour 5/16

Cups of sugar 3/16

5/8 more cups of flour we need for 6 servings

Step-by-step explanation:

Cups of flour

We need to divide the total of flour (1 1/4) in the total of servings (4)

=(1 1/4)/4

=5/16 cups of flour for servings

Cups of sugar

We need to divide the total of sugar (3/4) in the total of servings (4)

=(3/4)/4

=3/16 cups of sugar for servings

If the recipe is for 6 servings

You need to add more flour and sugar to complete 6 servings

1 1/4 flour=4 servings

x flour=6 servings

(1 1/4 flour*6 serving)/4 servings=x flour

x flour= 15/8 cups of flour

First 1 1/4 cups

Then 1 7/8

More cups of flour=5/8
