#10%#

Explanation:

If #$90# is #100%#, then #$9# would be #10%#.

This is because:

#$90# is #100%# because this is the total.
#$9# is #x%#

You can see that the #$9# is a tenth of the total value of #$90#, i.e:

#($90)/($10)=$9#

Therefore, the fraction of #1/10# is equivalent to #0.1# and this is the decimal representation of the percentage of #10%#.
