Fascinating little life hack, for doing percentages:
— Ben Stephens (@stephens_ben) 3 maart 2019
x% of y = y% of x
So, for example, if you needed to work out 4% of 75 in your head, just flip it and and do 75% of 4, which is easier.
Have a degree in Applied Mathematics and never knew that.

I'm really quite cross that this was NEVER taught in my maths class.
