Question

Sally is making browies and the recipe calls for (2)/(3)cups of oil. If sally already put in (1)/(4)cups of oil how much more is needed?

Answer 1

Sally needs an additional (5)/(12) cups of oil.

Step-by-step explanation:

To find out how much more oil Sally needs, we need to subtract the amount of oil she has already put in from the total amount needed. The recipe calls for (2)/(3) cups of oil, and she has already put in (1)/(4) cups. To find the difference, we can subtract (1)/(4) from (2)/(3):

(2)/(3) - (1)/(4) = (8)/(12) - (3)/(12) = (8-3)/(12) = 5/12

So Sally needs an additional (5)/(12) cups of oil to complete the recipe.
