Hi and thank you for your help.
Find the value of the following:
11!6! over 12!4!
If your answer is not an integer, write it as an exact fraction.
Thank you again
If you wrote out all the numbers for top and bottom...such
(11,10,...1) (6,5...1)/(12,11,10...1!(4,3...1)
cross out ever number than matches o the top and bottom. when finish you should have 6 and 5 left on the top and 12 left on the bottom
6*5/12
The answer should be 2.5
