1/9 was approximated as 0.111. Calculate the percentage error arising from this approximation.

Form Three Mathematics.
Topic-Errors and Approximation

---

Error made= Difference between the actual value and the approximated
Error=Actual value- approximated value
Error=1/9-0.111
Error=1/9-111/1000 (Note:0.111 into fraction)
Error=(1000-999)/9000 (l.c.m of denominators)
Error=1/9000
% error=(Error/Actual value)×100
% error={(1/9000)/(1/9)}×100
% error=(1/9000)×(9/1)×100
% error= 0.1%
