In the same vein, if the volume on your phone is on 1, and you increase it to 2, it has increased by 100%
I work in a place full of statisticians, and we've had to unfortunately have numerous conversations with some of them about the difference between "a decrease" and "a decrease in the rate." Apparently "it's increasing slower" isn't clear enough for some.
Maybe I'm understanding wrong but a decrease in the rate would be the derivative of a decrease. Aka the slope of the line. So if you are decreasing at -x. Rate of decrease is -1.
Unless I follow your wording incorrectly. Obviously it isn't always so nice of a function in real stats. Is that what they are missing?
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
Convert percentage to fraction, i.e, 80% become 0.8
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
I think it's ambiguous and the 90% actually makes more sense. If you increase something by 5m you are taking the original value and adding 5m to it. For multiplication you should probably avoid the word increase and say scaled by instead. 10% scaled by 180% is 18%.
