Answer:
Ms. Perry needs to make an additional 1/24 kg of fudge.
Explanation:
Ms. Perry has a total of 8/8 + 1/6 = 13/6 kg of fudge. She needs 1 1/8 kg of fudge for the brownies, which is equivalent to 9/8 kg. To find how much more fudge she needs to make, we can subtract the amount of fudge she already has from the amount she needs:
9/8 - 13/6 = 27/24 - 26/24 = 1/24
Therefore, Ms. Perry needs to make an additional 1/24 kg of fudge.
