9 3/4

Explanation:

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
