The recipe calls for 4 3/4 cups of flour of flour she has 2 2/3 how much more flour does she need?

2 1/12 more flour

Step-by-step explanation:

so we need to find the difference of the two so we do 4 3/4- 2 2/3, but we need to find the common denominater which is 12. now it becomes 4 9/12 - 2 8/12(because we multiply 3/3 to 3/4 and 4/4 to 2/3) which becomes 2 1/12 because 4-2 is 2 and 9/12- 8/12  is 1/12.
