In the following complex fraction, the entire fractions are cancelled. I’m not sure how to do this fraction. There are no adequate examples in any of the source materials available to me. Would you show how this is done using braille dots? See attached example:
Interestingly, the raised power of 3 is missing from this step, but .. brailling what I see .. each 4/3pi is canceled, and cancellation requires a spatial arrangement, so here is how to transcribe this step. (See attached file–sorry I answering from an old computer so I must send a .bmp file. Let me know if you can’t open it.)
