#9 3/4#

#color(blue)("Preamble")#

The symbol % is a bit like a unit of measurement but one that is worth #1/100#

so #39%" is the same as "39xx1/100=39/100#

In the same way that (as an example)

#40/100 =40xx1/100 = 40 xx% = 40%#

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#color(blue)("Answering the question")#

39% of 25 is the same as #39/100xx25#

You can write this as #39xx25/100#

but #25/100# is the same as #1/4# giving:

#39xx1/4" "=" " 39/4" " =" " 9 3/4#
