A 3-page .pdf file is attached for you to view 3 different possibilities.
1. You could use lead lines and stagger the labels over 2 lines of braille.
2. You could rotate the image so that the labels fit.
3. You could use a key for one or two of the fractions. This should only be used if the key is on the same braille page as the graphic. It is not the best option, as the student would have to refer back to the key.
