Final answer:
The average daily change in the pond's water level is calculated by dividing the total change (28 centimeters) by the number of days (7), resulting in an average recession of 4 centimeters per day.
Step-by-step explanation:
To represent the change in the pond's water level over a 7-day period using division, we can calculate the average change per day. The pond receded 28 centimeters in 7 days, so to find out how much it receded per day, we divide the total change by the number of days.
28 centimeters ÷ 7 days = 4 centimeters per day
Over the 7-day period, the pond's water level decreased by 28 centimeters. To represent this change, you can use the division , yielding an average decrease of 4 centimeters per day. This calculation provides a clear depiction of the daily rate at which the water receded.
The negative sign indicates the reduction in water level, emphasizing the downward trend over the specified time frame.
This division shows that on average, the pond's water level went down by 4 centimeters each day.
