I don't remember what rules or tricks I was taught about percentages, but I do remember realising that "%" meant "/ 100" and from there everything else followed.
- asgard1024 11y agoI went to elementary school in Czechoslovakia, late 80s, and we learned some rules about percentages (which I believe was just a modified formula with the multiplication by 100) as a part of what you call cross-multiplication.
- SixSigma 11y agoBut it doesn't mean / 100, it means "per 100" as described here in "The history of the percent sign" http://www.shadycharacters.co.uk/2015/03/percent-sign/ http://www.shadycharacters.co.uk/2015/03/percent-sign/
