#= 25/34#

Explanation:

First we add the 5 and 12 together to get
#5/17*2.5#

Next we make 2.5 whole number. Since 2.5#=2.5/1#, we multiply the numerator and denominator by 2 to get
#2.5/1 *2 = 5/2#
We then put #5/2# into the equation, to get
#5/17 *5/2#
The last step we do is multiply the tops and bottoms together. #5*5# is 25, and #17*2# is 34, which means
#5/17 *5/2 = 25/34#
This cannot be simplified any more, and is the answer.

I hope I helped!
