Final answer:
To share 1/2 a pan of Mac and cheese among 6 people, the division expression would be (1/2) ÷ 6 or 1/2 × 1/6, resulting in each person getting 1/12 of the pan.
Step-by-step explanation:
The division expression for how 6 people share 1/2 a pan of Mac and cheese would be (1/2) ÷ 6. This means you are taking the half pan of Mac and cheese and dividing it into 6 equal portions for each person. To calculate the amount each person gets, you divide 1/2 by 6, which can also be written as 1/2 × 1/6. Simply multiply the numerators together and the denominators together to find the answer, which is 1/12.
Therefore, each person would get 1/12 of the pan of Mac and cheese.
