The answer is that there was 1/12 of the lasagna left. This is because you subtract 1/6 from 1/4. Then, you find the least common factor of 6 and 4 which is 12. Subtract and your final answer will be 1/12.
1/4-1/6 Find the least common factor of 4 and 12 3/12-2/12 Subtract Final Answer: 1/12

Now, at the end, you have 5 of them left. So you have five of the original 24—.
