Hello,

100 x 1.1 = 110
100 : 0.9 = 111.11

Is A x (1 + B/100) equal to A : (1 - B/100)
Let A be the initial value and B the percentage to achieve.

In terms of calculating percentage increases and decreases.
Could you explain to me why I don’t get the same result?
To me, it’s the same thing, that is to say a 10% increase.
Thank you.

Good evening

This conversation has little to do with office automation...
However
There is nothing to explain
Multiplying by 1.1 corresponds to adding 10%
Multiplying by 0.9 corresponds to subtracting 10%
Dividing by 0.9 corresponds to nothing (except adding about 11.11111%!!!)

Dividing any number a by a number b that is not zero is equivalent to multiplying the number a by the inverse of the number b
0.9 does not have 1.1 as its inverse... The inverse of 0.9 is 1.11111111111 (from 1 to infinity).
