3b+2(b-1) = 8
3b+2b-2 = 8
5b = 8+2
5b = 10
b = 2

I'm not going to give you the answer, but I can try to help you. A common denominator, I think, is like when you try to find out the number they all multiply. Like, for example, 9. 1, 3, 9, etc. are numbers you can use to either multiply up to 9, or more than 9. I don't know if I even make sense. Just do a good amount of research.
As you can see in the denominator, the values keep on multiplying by 2, meaning that the number must multiply by 0.5 or 1/2 to get the next one.
So the rule is *1/2.
