First of all, you should remember that:
[tex]2=\frac{2}{1}[/tex]
All number is equal to that number divide by 1. Like the example of 2.
After that we apply the next law (i draw it):
First you represent the numerator of fraction (2) in a fraction number 2/1... because is the same like I told you before.
After that, You multiply the numbers at the extreme (light blue) 2 * 11 and put that result at the new numerator.
Later, the numbers in the inside will be multiplied (dark blue) 1*3 and put that resoult in the denominator.
Finally, you simplify if you can. This isn't the case. And that's it.
