I don't get it. Is this supposed to be a puzzle? [imath](13.08 \div10) -1 =30.8\%[/imath].
You just showed what I did, and rounded up to 31%. That contradicts your 30%? I don't understand?\(\displaystyle (13.08 \div 10) - 1\ \)
\(\displaystyle = \ 1.308 - 1 \ \)
\(\displaystyle = \ 0.308 \ \)
\(\displaystyle = \ 30.8\% \ \)
\(\displaystyle \ \approx 31\% \)
