I have 2 problems that I just need to know if they are right
1. Add, Simplify if possible
3/14w + 11/49w
Answer that I got was
21+22/98w
2. Add, simplify if possible
9b/3b9 + 6b/9b27
I am not sure about this one
I got two answers
81b+6b/34b108 or
87b/34b108
please help

1. is correct, but not completed:
(21+22)/98w (careful to use the brackets)
=43/98w
2. I went wrong on this one myself, by taking the question down wrong, but I have it straight now.
Divide 6b/(9b27) top and bottom by 3. You can do that without changing its value. So
6b/(9b27) = 2b/(3b9)
Now you're left with 9b/(3b9) + 2b(3b9) and I'm sure you can see your way from there.
