Arecipe uses 1 1/4 cups of oil to make 20 servings. if the same amount of oil is used for each serving, how many servings can be made with one gallon of oil ?

Step-by-step explanation:

1 1/4 (or 1.25) cups to 20 servings = 1 gallon (16 cups) to x servings

 1.25        16

=  cross multiply

 20           x

(1.25)(x) = (20)(16)

1.25x = 320

x = 320/1.25

x = 256 servings <===
