The context that describes a difference of rational numbers is finding the average of daily high temperatures.
The context that describes a difference of rational numbers is "finding the average of daily high temperatures."
To determine the average of daily high temperatures, you would need to add up all the daily high temperatures and then divide the sum by the number of temperatures. The average of daily high temperatures can be represented as a rational number, which is a number that can be expressed as a ratio of two integers.
In this context, you would be comparing and finding the differences between the individual daily high temperatures, calculating their sum, and then dividing by the total number of temperatures. The result would be a rational number that represents the average of the daily high temperatures.
