I have 2 problems that I just need to know if they are right
3/14w + 11/49w
21+22/98w
9b/3b-9 + 6b/9b-27
81b+6b/34b-108 or
87b/34b-108

1. jim

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/(9b-27) top and bottom by 3. You can do that without changing its value. So

6b/(9b-27) = 2b/(3b-9)

Now you're left with 9b/(3b-9) + 2b(3b-9) and I'm sure you can see your way from there.
