((13,75+9*1/6)1,2))/((10,3-8*1/2)5/9)= $\frac{( \frac{1375}{100}+9*\frac{1}{6}* \frac{12}{10})}{ (\frac{103}{10}-8* \frac{1}{2}* \frac{5}{9} ) }= \frac{ \frac{1375}{100} + \frac{9*1}{6}*\frac{12}{10}}{\frac{103}{10}-\frac{8*1}{2}*\frac{5}{9}}=\frac{ \frac{1375}{100}+\frac{9}{6}*\frac{12}{10}}{\frac{103}{10}-\frac{8}{2}*\frac{5}{9}} =\frac{\frac{1375}{100}+\frac{9*12}{6*10}}{\frac{103}{10}-\frac{8*5}{2*9}}=\frac{\frac{1375}{100}+\frac{108}{60}}{\frac{103}{10}+\frac{40}{18}}=\frac{ \frac{1375*3}{100*3}+ \frac{108*5}{60*5} }{ \frac{103*9}{10*9}- \frac{40*5}{18*5}}= \frac{ \frac{4125+540}{300} }{ \frac{927-200}{90}}= \frac{ \frac{4665}{300}}{ \frac{727}{90}}= \frac{4665*90}{300*727}= \frac{419850}{218100}= \frac{2799*150}{1454*150}= \frac{2799}{1454}=$ $=1 \frac{1345}{1454}$
