very similar to the other question you had
http://www.jiskha.com/display.cgi?id=1422645251
10!11!/(7!13!)
= (10x9x8x7! 11!)/(7! 13x12x11x10!)
= 10x9x8/(13x12x11) (after the 7!10! cancel)
= 60/143

10!11!/(7!13!)
= (10x9x8x7! 11!)/(7! 13x12x11x10!)
= 10x9x8/(13x12x11) (after the 7!10! cancel)
= 60/143
