Which of the following fractions has the greatest value?
A. 3/8!
B. 6(4!) / 5(9!)
C. 4(3!) / 9!
D. 3 / 5(7!)
E. 14 / 5(8!)
Where do I start? I can't see any similarities to narrow the down the answer.

A. 3/8! = 3 x 9 / 9!
B. 6(4!) / 5(9!) = ((6 x 4!)/5)/9!
C. 4(3!) / 9! = 4!/9!
D. 3 / 5(7!) = (3 x 8 x 9 /5)/9!
E. 14 / 5(8!) = ((14 x 9)/5)/9!

Just because something is hard doesn't mean you shouldn't try,it means you should just try harder.

Yeah,surely.kstv wrote:The denominator can be manipulated to become 9! 8! or 7!. Then the common denominator can be cancelled.
Infact I made it 8!
And it is solvable.
I took 9! because I find multiplication easier than division.
