#5/2 = 2.5 = 2times1/2#

Explanation:

I am just guessing since you did not write in acceptable format. Half of 5.

#1/2times5 = 5/2 = 2.5 = 2 1/2#

#5/2#

Explanation:

Did you know that you may (if you so wish) write 5 as #5/1#. This is not normally done but it is correct.

#color(green)(1/2)xx color(red)(5/1)=( color(green)(1)color(red)(xx5))/(color(green)(2)color(red)(xx1)) = 5/2#
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Alternatively:

Note that #1/2xx5# is the same as #5xx1/2#

So we have 5 lots of #1/2#

#= 1/2+1/2+1/2+1/2+1/2color(white)("d")=color(white)("d")(1+1+1+1+1)/2color(white)("d")=color(white)("d")5/2#
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
However: #5/2 color(white)("d")=(2+2+1)/2color(white)("d")=color(white)("d")color(white)("d")2/2+2/2+1/2color(white)("d")=1+1+ 1/2 = 2 1/2#
