Number 3 i am so stuck help plz

Answer 1

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

Subtract
Final Answer: 1/12

Answer 2

Okay, think of it as a pie. They ate 3/4 of the pie, leaving 1/4. Then that 1/4 was cut into 6/6, and 1/6 was eaten. So there were 5/6 left of that 1/4. Your pie has 4 quarters, and each is made up of 6 mini pieces, so 6 x 4 = 24. There were 24 little 1/6 pieces at the beginning when your lasagna pie was whole. Now, at the end, you have 5 of them left. So you have five of the original 24—$\frac{5}{24}$.
