I have a long spread sheet in which I merged 3 columns together in faction format. Using this formula =CONCATENATE(A2," ",B2," ",C2). The problem is its converting my factions into a decimal or number format. I've tried the format function in column D but it doesn't convert back to a fraction. Does anyone know how to convert column D back into a fraction format? Or better yet keep it from converting from a fraction to number to begin with with. Any solutions would be greatly appreciated.

Thank you in advance

Ex: Combined Columns A / B / C = D

A = 11 1/8 B = x C = 31 1/2 D= 11.125 x 31.50

Need to be: D= 11 1/8 x 31 1/2
