sorry if I was unclear. I'm not good at latex
+118608 Your answer is very clear. 
If you want help with Latex this is a good site to start on. What you have written would not be terribly difficult in LaTex but to start,
the fraction 1/2 is just
\frac{1}{2}
\frac means that what follows is to be written as a fraction.
The numerator goes in the first set of parentheses and the denominator goes in the second set.
Easy peazy.
=\(\frac{1}{2}\)
