trick_1:
if you want ansere like 475/5, then the numerator becames 95, and denominator becames 1.
for getting answer 95, you can use this formula
=RIGHT(TEXT(A1,"? ?/?"),LEN(TEXT(A1,"? ?/?"))-FIND("/",TEXT(A1,"? ?/?")))
or
=RIGHT(TEXT(A1,"? ?/????????"),LEN(TEXT(A1,"? ?/????????"))-FIND("/",TEXT(A1,"? ?/????????")))
trick_2:
numerator
=LEFT(TEXT(A1,"???/???"),FIND("/",TEXT(A1,"???/???"))-1)+0
denominator
=RIGHT(TEXT(A1,"???/???"),FIND("/",TEXT(A1,"???/???"))-1)+0
