One context that describes a difference of rational numbers is when comparing the temperatures of two cities. For example, if the temperature in City A is 25 degrees Celsius and the temperature in City B is 10 degrees Celsius, the difference in temperatures between the two cities is 15 degrees Celsius.
The difference of rational numbers is the result obtained when subtracting one rational number from another. In other words, it is the numerical value that represents the distance between two rational numbers on the number line. This difference can be positive, negative, or zero, depending on the magnitudes and signs of the numbers being subtracted.
