Answer:

18

Explanation:

In the same way that inches, centimetres, miles and kilometres are unit of measurement so is % a unit of measurement. When you see % think of #1/100#. So percent is measuring in hundredths.

Consequently #50%" is the same as "50xx1/100=50/100#

In the same way that 2 of something is the same as #2xx" something,"# 50% of 36 is the same as #50/100xx36#

But #50/100" is the same as "(50-:50)/(100-:50) =1/2#

So 50% of 36 is the same as #1/2xx36 = 18#
