    You just need to find a common denominator.
     
  4. That's for division by a fraction, in which case you multiply by the reciprocal.

    Since the two denominators are x+2 and x+3 the common denominator will be (x+2)(x+3).

    It's just like 1/2+ 1/3= (1/2)(3/3)+ (1/3)(2/2)= 3/6+ 2/6= 5/6.
