 My question was how to make three different kinds of fraction. 

First kind (<mafrac>, <divide>) is rendered like 
<munderover>
 <mi>-</mi>
 <mi>b</mi>
 <mi>a</mi>
</munderover>

Second kind (<mi>a</mi><mo>/</mo><mi>b</mi>) is rendered like 'a/b' in plain text i.e. 'a' and 'b' are located on the same level ('/' is stretchy)

And the third kind is something in the middle.
Some fonts have single character for 1/2 (and/or 1/4)
I have attached a gif file with all three kinds.
