The correct context that describes a difference of rational numbers is comparing the daily high temperature and low temperature.
The correct response that describes a difference of rational numbers is "finding the average of daily high temperatures."
To understand why this is the correct answer, we need to first understand what rational numbers are. Rational numbers are numbers that can be expressed as a fraction, where the numerator and denominator are both integers (whole numbers) and the denominator is not zero. For example, 3/4, -5/2, and 1 are all rational numbers.
In the context of finding the average of daily high temperatures, we are dealing with a collection of numbers that represent the high temperatures of each day. These temperatures can be any real numbers, including both rational and irrational numbers. However, when we calculate the average of daily high temperatures, we are summing up all the temperatures and dividing by the total number of days, which results in a rational number.
For example, if we have daily high temperatures of 75, 82, and 70 degrees Fahrenheit for three days, we can find the average by adding them up (75 + 82 + 70 = 227) and dividing by 3 (since there are three days). This results in an average of 75.67, which is a rational number.
In contrast, the other contexts mentioned in the responses do not necessarily involve rational numbers. Comparing the daily high and low temperatures, recording the temperature hourly, and determining the coldest temperature in a month can all involve any real numbers, including both rational and irrational numbers.
