Question: What is the sum? Explain the steps to add them and check if the result can be simplified.
Sample answer: The sum is . I added the numerators over the common denominator. Then I checked if the numerator and denominator share any common factors. They do not, so the fraction is fully simplified.
Key points:
- Combine the numerators over the common denominator to get .
- Check the numerator and denominator for common factors.
- Conclude that the fraction is already fully simplified.
Rubric: A correct answer includes the sum , explains combining numerators over the common denominator, and mentions checking for factors to see if it simplifies.
