So we can finally finish the math example from the HolQeD article with javlogh boqHa''egh wej; chen jav loch wej. (I'm assuming that fractions work as a unique type of noun phrase in sentences even though they're constructed as complete sentences. Otherwise they would be quite difficult to actually use.)

I wouldn't assume that. You might have to say javlogh boqHa''egh wej; chen jav lochbogh wej. Which is about as informative as "three divided by six is three-sixths." Anyway, a more sensible speaker would reduce the fraction: javlogh boqHa''egh wej; chen cha' lochbogh wa'.
