Hi,

if you have 100% of something and want to know how much 75% of this is (i.e. subtracting 25%). You multiply it by 75 and divide what you get on 100. That gives you the 75% value which means you have subtracted 25%.

If you want to make it easier you can multiply the 100% value by 0,75, which will give you the same answer (meaning that you divide 75% on 100 before you multiply.

Hope that was helpful(:
