Final answer:
A real-world financial situation of a business is used to create a list of rational numbers. Using a number line to order the values from negative to positive helps in understanding the business's financial status.
Step-by-step explanation:
Creating a real-world situation with at least four rational numbers, let's consider a small business's financial transactions on a particular day. The following transactions occur: a sale adding $25.50 to the business (a positive decimal), purchasing supplies costing -$15.75 (a negative decimal), receiving a payment of 3/4 of a deposit owed (a positive fraction), and paying back 1/2 of a loan (a negative fraction).
To order these rational numbers on a number line, first convert all of them to decimals. The positive fraction 3/4 becomes 0.75, and the negative fraction -1/2 becomes -0.5. Now we have the numbers $25.50, -$15.75, 0.75, and -0.5. To place them on the number line, find each decimal's position relative to zero, with negative numbers to the left and positive numbers to the right. Now list the values from least to greatest: -$15.75, -0.5, 0.75, $25.50.
Comparing and ordering the numbers reveals the financial status of the business throughout the day, giving insight into its cash flow. This also helps in understanding the impact of positive and negative transactions on the overall finances.
