With this you can use another technique of multiplying by the closest 5 or 10 and minusing the multiplied difference for complex calculations: Eg 7% of 23
7x25=175
175-14=161
161/100 =1.61
Practice and you'll pull off some impressive quick maths in a meeting.

Did they even teach this in school? I feel like I would’ve remembered it.

So the 15% tip on a $162 dinner tab is the same as 162% of 15.

% just means "multiple by me and divide by 100"
8x25=200
200/100=2
