6! = 1*2*3*4*5*6
3! = 1*2*3
2! = 1*2 = 2
so 6!/3!2! = 2*3*4*5*6/(2*3*2) = 4*5*6/2= 4*5*3 = 60

6! / 3!2! = 6 x 5 x 4 x 3 x 2 x 1 / 3 x 2 x 1 x 2 x 1
From there we can cross out the common numbers which gives us:
6 x 5 x 4 / 2 x 1 = 120 / 2 = 60.

6! = 6 x 5 x 4 x 3 x 2 x 1
so are 3! and 1!
6x5x4x3x2x1 / (3x2x1)(1) =120

6! / 3! * 2!
= (6 * 5 * 4 * 3 * 2 * 1) / (3 * 2 * 1) * (2 * 1)
= (6 * 5 * 4) / 2
= 120 / 2
= 60.

The "!" is the factorial function. 6! = 6x5x4x3x2x1 = 720. When doing division 6!/3!2! is equal to 6x5x4x3x2x1/ 3x2x1x2x1. You can do some cancellation right off the bat and get 6x5x4/2x1 Some quick division will give you 6x5x2/1x1 which is just 6x5x2, which equals 60.

(6!)/(3! 2!) = 6*5*4/(2!) = 6*5*2 = 60

Assume question is:-
6 ! 2!
------
3!
= 6 x 5 x 4 x 2
= 240
However, you may mean:-
6! / (3! 2!)
(6 x 5 x 4) / 2
120 / 2
60
Bottom line is that question is unclear due to lack of brackets.

(6*5*4*3*2*1) / ((3*2*1)*(2*1))
which will give you 60

When you see something like 6!...that means 6 factorial, or 6X5X4X3X2X1. So in your equation it would become:
720/(6X2) = 720/12 = 60
Answer = 60
