thanks and hope you like the answer
Oh hai.
I made the exercise as well and got the same answers :). But I think there's the problem that you can only have is that you can only have 3 SG in your answer, because your masses have 3 SG as well. Therefore, the results would be the same. This is what I think, but I'm not an expert. However, I think that the way in which you solved the problem is very solid!
