#%100#

#9/9=9/9xxcolor(red)100/100#
#color(white)(x)=color(red)100/100#

Therefore it is #100# percent.

#100#

#color(blue)("9% of any number"# can be expressed as #color(blue)(9/100x#.

Thus, if #"9% of some number"# is equal to #9#, we can say that

#9/100x=9#

To find the unknown value, #x#, multiply both sides by #100/9#.

#x=100/9*9#

#x=100#

Therefore, #"9% of 100"=9#.
