The word processor let me do this as just text but I had to use centre centre justify the fraction option ...I have attached example dgn and also picture
type out what you want with the divisor bar then highlight the fraction part of your text and use the the A1/2 pull down see my circled picture and I chose the middle one.. for the one with the H1/H2 I used a differnt font size in the same piece of text ... was easier than I first thought it would be..
Download my dgn file and copy and edit what you want... until you can do it yourself .. took me 10 mins to figure out and 20 mins to figure out how to tell you and upload it...
