# How do you reduce 68 by 12.5%?

Jun 9, 2018

$59.5$

#### Explanation:

There are two methods.

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

12.5% xx 68

$= \frac{12.5}{100} \times 68 = 8.5$

$\therefore 68 - 8.5 = 59.5$

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

100%-12.5% = 87.5%

$\frac{87.5}{100} \times 68$

$= 59.5$

Note that the percentages 12.5% and 87.5 are the same as the fractions $\frac{1}{8} \mathmr{and} \frac{7}{8}$
