This is a different sort of 10-in-9 puzzle, using fractions instead of 2-digit numbers.
Fill the grid with numbers so that every row, column, and 3x3 box contains each of the 10 digits, from 0 to 9, exactly once: Eight cells contain 1-digit numbers (from 0 to 9), and the other cell contains a fraction of the form A/B where A is a digit from 1 to 9 and B is a digit from 2 to 9. Each fraction must be in lowest terms; i.e. A and B have no common factor larger than 1. For example, 3/2 is permitted, but the equivalent fractions 6/4 and 9/6 are not.
In each cage indicated by the dotted lines, the number at the top left is the sum of the numbers in the cage. Also, no digit can occur more than once in a cage, whether it's alone in a cell or the numerator or denominator of a fraction. For example, a cage might contain 1/2, 3/5, and 4, and its sum would be 51/10. But all the sums in this puzzle are integers, and figuring out how that's possible is part of the puzzle.
The puzzle is available on Penpa. To enter a fraction, choose "Number" and "L" and type, for example, "1/2". It won't work if you use "Number" and "Normal".
Lösungscode: Column 2 and column 8. Include the "/" in each fraction.

@Nylimb that happens because in addition to the "picture" tags, the author might add any number of text-tags to his puzzle and they are added to the database. Unfortunately, that only works in a small community with a low number of puzzles.

It took me a long time to figure out the possible fractions, but it was worth it.
Even after that, the rest were still extremely tricky.
Wonderful puzzle :)

@Ragna: I've edited your most recent hidden comment to give the example that you requested earlier.

@Realshaggy: Thanks for the information. I'll do that.

You can edit the comment with the question. Ragna can see his own hidden comment, even if he didn’t solve the puzzle yet. That’s how most people do it. Some people might not like the idea to unnecessarily edit other people’s comments or get their comments changed, but we were a rather small community for a long time, where most people know each other in person and didn’t care about such things. I think there is also an option in the user settings to get a mail if one of your comments is changed.

Can someone with more experience on this site answer a question for me?: If I write a hidden comment that starts with "@Ragna", will Ragna be able to see the comment before solving the puzzle? If not, is there some other way that I can reply to Ragna's question privately?

@Joe Average: Yes, the fractions are numbers that contribute to the sum of a cage. For example, if a cage contained 1/2, 3/5, and 4, its sum would be 51/10. But all the sums in this puzzle are integers, and figuring out how that's possible is part of the puzzle.

@Ragna: Did you see the hidden comment that I wrote yesterday? It gives an example that answers your question.
If you can't see hidden comments, is there some other way I can contact you?

@Ragna: What do you want an example of?

@Realshaggy: Okay, I've hidden the comments, and I'll delete the spoiler alert.

I just don't understand why there is any need to discuss these things in public? The comments can also be seen in the "list of last comments", without your spoiler warning in the puzzle.

@Realshaggy: Is the spoiler alert that I added good enough, or do you still think I should hide the comments?

Please hide your comments. I want to find out the sums for myself and I think most other people too.
