So let's group like terms in the numerator:
  We can add terms like in the example.
   We can add terms like in the example.

Let's rearrange the denominator.

Now we have: 
 Cancel like terms
  Cancel like terms
4/8 = 1/2     
 = 1  So it cancels
 = 1  So it cancels
 = s Since s is raised to the -1 it goes on top and becomes s.
 = s Since s is raised to the -1 it goes on top and becomes s.

Now we combine everything back together:
