#85%# of #900/17# is #45#

#85%# is equivalent to #85/100#

Let #85%=85/100# of #x# be #45#

Hence #85/100xx x=45# or

#85/100xx x xx100/85=45xx100/85# or

#cancel85/cancel100xx x xxcancel100/cancel85=45xx100/85# or

#x=45xx100/85# or

#x=5xx9xx100/(5xx17)# or

#x=cancel5xx9xx100/(cancel5xx17)# or

#x=9xx100/17=900/17#
