A context that describes the difference of rational numbers could involve comparing quantities in real-life situations, such as financial transactions, measuring lengths, or comparing temperatures. Here’s an example:
Financial Context: Imagine you have two bank accounts. In Bank A, you have $250. In Bank B, you have $175. If you want to find out how much more money you have in Bank A compared to Bank B, you would calculate the difference between the two amounts:
\[ \text{Difference} = \text{Amount in Bank A} - \text{Amount in Bank B} = 250 - 175 = 75 \]
In this scenario, both $250 and $175 are rational numbers, and their difference is also a rational number, showing how the context of managing finances provides a clear example of subtracting one rational number from another.
