$g) 5,2+5,(2)-5,02-5,0(2)=\frac{52}{10} +\frac{52-5}{9} -\frac{502}{100} -\frac{502-50}{90} =$

$=\frac{52}{10} +\frac{50}{9} -\frac{502}{100} -\frac{452}{90} =$

$=^{90)} \frac{26}{5} +^{50)} \frac{50}{9} -^{9)} \frac{251}{50} -^{10)} \frac{226}{45} =$

$=\frac{234+2500-2259-2260}{450} =$

$=\frac{321}{450}$
