#455.56#

Explanation:

#82/x# is equal to #18/100.#

Cross mulitply.

#8,200=18x.#

Isolate the #x# by dividing by #18# on both sides.

So, #455.56# (or #455.bar5#) is your #x# value, which is what #82# is #18# percent of.

#455.dot5# or #4100/9#

Explanation:

#18=82#

#18% =18/100=9/50#

which means

#9/50x=82#

solving this equation for x

#cancel(50/9*9/50)x=82*50/9#

#x=4100/9# or in decimal #455.dot5#

#455.dot5 = 455.5555555555...#

The number is #455 5/9#

Explanation:

You can write an equation.

#18%# of some bigger number (#x#), will give an answer of #82#

#18% xx x = 82#

#18/100 xx x = 82#

#color(white)(xxxxx)x = (82 xx 100)/18#

#color(white)(xxxxx)x = (82 xx 100)/18#

#color(white)(xxxxx)x = 455 5/9#
