I can't get this problem, and the guides atre no help...
Could someone please explain this to me?
I have this problem:
-1,8/1,5 - 5,1
and
3,6/2,1 + 0,3
How do you add or subtract the denominators?
Thanks.

Are you using comma (",") as a decimal point (".")?

Yes, sorry if caused misunderstanding.
 
Can you evaluate the following:

\(\displaystyle -\frac{18}{15} - 51 = ??\)
