Answer:

#59.5#

Explanation:

There are two methods.

  • You can find how much #12.5%# of #68# is and then subtract it:

#12.5% xx 68#

#=12.5/100xx 68 = 8.5#

#:. 68-8.5 = 59.5#

  • Realise that a reduction of #12.5%# is the same as finding #87.5%#

#100%-12.5% = 87.5%#

#87.5/100 xx 68#

#=59.5#

Note that the percentages #12.5% and 87.5# are the same as the fractions #1/8 and 7/8#
