taking a percentage of something essentially means multiplying it with a hundreath of the percentage
6% of 50 essentially means 50 * 0.06
or
50 * 6 * 0.01
and since
50 * 6 * 0.01 = 6 * 50 * 0.01
then of course
50 * 0.06 = 6 * 0.5
Yeah my brain just sees 5*6, and then I move the decimal. I never understood how people couldn’t figure out tips when they wanted 20%.
If you live in the U.S. you do them quite often, multiply by 2. Want 10 multiply by .1… Half that and add it if you want 15. Whatever is easiest at that moment
I prefer to keep it technically correct yet evil and confusing. 6% being a fancy way to write 0.06 or 6 * 1/100 means we can take 6 * 50 * 1/100 and simplify to 300 * 1/100 and then represent that as 300%.
That’s because multiplication is commutative

Finally a reasonable way to do percentages! Thank you, I’m stealing this
