Question 555017
as far as i can tell, your answer is number 4 in the attached diagram.
number 1 is my interpretation of your problem statement.
number 2 is the same equation after it has been factored and some obvious common terms in the numerator and the denominator have  been removed because they will cancel out.
number 3 is making a/(b/c) equal to a*(c/b) and then removing some more obvious common terms in the numerator and the denominator that will cancel out.
number 4 is the result.
