Convert percentage to fraction, i.e, 80% become 0.8 Then multiply with initial value

If it says 80% more use initial + (initial*80) or simply initial*1.8

Or if it says 80% less, use - in above calculation or multiply by 0.2

I find percentages more neat when used as fractional number Edited to escape the multiplication symbol

I said that to a friend of mine how to get percentage by creating fraction. They were flabbergasted at the sorcery.

The friend is a Doctrate of biological sciences and a professor. Where as I am just an engineer.

It's really not even converting, as percent is literally "1/100" (per-cent = per 100). It's purely convenient shorthand.

Yeah, the math straight up works in the fractional form

That's not a fraction.

⅘ is a fraction.

You know we say "a fraction of something" with a number(usually between 1 and zero) often denoted by letter epsilon. 4/5 equals 0.8 so there is nothing wrong in calling that a fraction too

Edit: Its called Decimal Fractions
