answer and explain

Explanation:

Step1: Calculate your rate

To find the rate (ornaments per minute), use the formula \( \text{Rate} = \frac{\text{Number of Ornaments}}{\text{Time in Minutes}} \). For you, the number of ornaments is 25 and time is 12.5 minutes. So your rate is \( \frac{25}{12.5} = 2 \) ornaments per minute.

Step2: Calculate your sister's rate

For your sister, the number of ornaments is 15 and time is 6 minutes. Using the same rate formula, her rate is \( \frac{15}{6} = 2.5 \) ornaments per minute.

Step3: Compare the rates

Your rate is 2 ornaments per minute and your sister's rate is 2.5 ornaments per minute. Since \( 2.5 > 2 \), your sister decorates faster.

Answer:

Your sister decorates faster because your rate of decorating is 2 ornaments per minute and your sister's rate is 2.5 ornaments per minute, and \( 2.5 > 2 \).
