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
