Based on the Fisher equation, if expected inflation ${}^e=2\%$ and nominal rate $r_{\text{n}\text{o}\text{m}\text{i}\text{n}\text{a}\text{l}}=13\%,$ what would the real rate rreal be$?$

Note: Show your answer in units of percents, use plain numbers with at least two digits after the decimal $($e$.$g$.,$ for $12\mathrm{.}34\%,$ type $12\mathrm{.}34).$
