The naive way is to first calculate 10% of the given number and then subtract it from that number.
The smarter way is to recognise that subtracting 10% is the same as leaving (100-10) = 90 percent. Since 90% is 0.9, simply multiply the given number by 0.9
So, for example suppose you wish to subtract 10% from 67.3
Method I:
10% of 67.3 is 67.3*10/100 = 67.3*0.1 = 6.73
then 67.3 - 6.73 = 60.57
Method II
90% of 67.3 is 67.3*90/100 = 67.3*0.9 = 60.57
