\(\dfrac{1}{2}+x:25\%+x:0,01=\dfrac{109}{10}\\ \Rightarrow x:\dfrac{1}{4}+x:\dfrac{1}{100}=\dfrac{109}{10}-\dfrac{1}{2}\\ \Rightarrow x\times4+x\times100=\dfrac{109}{10}-\dfrac{5}{10}\\ \Rightarrow x\times\left(4+100\right)=\dfrac{104}{10}\\ \Rightarrow x\times104=\dfrac{104}{10}\\ \Rightarrow x=\dfrac{104}{10}:104\\ \Rightarrow x=\dfrac{1}{10}\)
