Very much old school here, rather than say working out the full equation can be tedious isn't always true. you can whittle alot of the maths by removing extraneous factors from top and bottom (numerator and denominator).
Eliminating 3x2x1 from top AND bottom leaves you with
(5x4) / (2x1) = 20 /2 = 10 .... not that hard.

Brilliant - Thanks.
Maybe a little bit overly simplified (I just wanted to know a quicker way of doing this on the calculator), but useful none the less! : )
