Hi when calculating the sort ratio, I used Model B lost cost / Model A LC instead of A/B, and following the same subsequent steps. However, I got different answers than the solution. Is this incorrect? Thank you

If you compute the sort ratio as Model B / Model A then your deciles will be in reverse compared to when you compute using Model A / Model B. This is fine. You should verify that your 1st decile matches the 10th decile of the solution, your 2nd matches the 9th, and so on.
You should still arrive at the same conclusion regarding which model performs best.
