Which part is most appropriately matched with its unit?(1 point) Responses 18 of a week (a week is 7 days) Start Fraction 1 over 8 End Fraction of a week (a week is 7 days) 12 of a foot (a foot is 12 inches) Start Fraction 1 over 2 End Fraction of a foot (a foot is 12 inches) 3% of a pint (a pint is 16 ounces) 3% of a pint (a pint is 16 ounces) 0.2 of a year (a year is 365 days)

To determine which part is most appropriately matched with its unit, let's analyze each option:

1. **18 of a week (a week is 7 days)**: This is not appropriate because 18 is more than the total days in a week.

2. **Start Fraction 1 over 8 End Fraction of a week (a week is 7 days)**: Calculating this gives (1/8) * 7 = 0.875 days, which is appropriate but not a common use case for a week.

3. **12 of a foot (a foot is 12 inches)**: This is appropriate, as it correctly matches the definition of a foot (there are 12 inches in a foot).

4. **Start Fraction 1 over 2 End Fraction of a foot (a foot is 12 inches)**: This is also correct, as (1/2) * 12 = 6 inches, which is indeed a valid measurement.

5. **3% of a pint (a pint is 16 ounces)**: This gives (3/100) * 16 = 0.48 ounces, which is appropriate but again not the most common context.

6. **0.2 of a year (a year is 365 days)**: This means 0.2 * 365 = 73 days, which is a valid measurement but not specifically tied to a unit frequently.

Based on this evaluation, the best match is:

**12 of a foot (a foot is 12 inches)**, as it directly aligns with the definition of a foot.
