Question

How do you reduce 68 by 12.5%?

Answer 1

`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`
