Just multiply the top two together and the bottom two together and reduce the answer.
The first one think of as
1/12 * 6/1 =
(1*6)/(12*1) =
6/12 = 1/2

2/3*3/8 =
6/24 =
1/4
If you want to get a little bit fancy you can cancel top and bottom before you multiply.
2/3*3/8 =
2/1*1/8 =
1/1*1/4 =
1/4
 
ya, mom; just remember that:

a/b times c/d = (a times c) / (b times d)

That's same as: (a/b)(c/d) = (ac) / (bd) : standard way to "type" those
