I met several GRE numeric entry questions which ask to type in my results nearest to $0.1 \%$ or $0.01 \%$ or $0.1 $ or $0.01 $
Ex.: After calculations I found that $a=\frac{110}{95}$b and the question is what percent of quantity b, quantity a is greater?
Thus $a=(1.1578..)b$ and I need to write this to the nearest $0.1 \%$. How do I do that and also what is the difference between nearest to $0.1 \%$ and nearest to $0.1 $
When you are asked to write your result to the nearest $0.1$ you are asked to write a value rounded to the first decimal digit. In your example the result would be $1.2$.
On the other hand, when you are asked to write your result to the nearest $0.1\%$ you are asked to write a percentage value rounded to the first decimal digit (although personally I don't like this formulation). In your example the result would be $115.8\%$.
