It does not have an equivalent version (with a denominator of 9) and an integer numerator.
Occasionally you may find a teacher looking for (or accepting) fractions with numerators (or denominators) which are themselves fractions.
In this case, we would have the required ratios: ##color(white)(“XXX”)54/8=x/9##
##color(white)(“XXX”)rArr 8x=54xx9=486##
##color(white)(“XXX”)rArr x=486/8=243/4##
and ##54/8 = (243/4)/9##
