Final answer:
A real-world problem involves friends at a party sharing pizza slices. Using the equation (9/12) - (8/12), we found that each person took 1/12 of a slice initially.
Step-by-step explanation:
Let's consider a real-world problem where you have 9 slices of pizza divided equally among 12 friends at a party. After everyone has taken their slices, there are 8 slices left. To solve how many slices each person initially took, we use the equation (9/12) - (8/12).
To solve for the initial slices taken per person, we do the following steps:
- Subtract the fractions: (9/12) - (8/12) = 1/12.
- Each person took 1/12 of a slice of pizza.
So initially, each person took 1/12 of a slice from the 9 slices available.
