x+8\tt\displaystyle\frac{1}{11}=16,1\\\\

x+8\tt\displaystyle\frac{1}{11}=16\frac{1}{10}\\\\

x=16\tt\displaystyle\frac{1}{10}-8\frac{1}{11}\\\\

x=16\tt\displaystyle\frac{11}{110}-8\frac{10}{110}\\\\

x=8\tt\displaystyle\frac{1}{110}\\\\

===================

y-9,7=8\tt\displaystyle\frac{2}{3}\\\\

y=8\tt\displaystyle\frac{2}{3}+9,7\\\\

y=8\tt\displaystyle\frac{2}{3}+9\frac{7}{10}\\\\

y=8\tt\displaystyle\frac{20}{30}+9\frac{21}{30}\\\\

y=17\tt\displaystyle\frac{41}{30}\\\\

y=18\tt\displaystyle\frac{11}{30}\\\\

===================

100,3+x=102\tt\displaystyle\frac{1}{6}\\\\

100\tt\displaystyle\frac{3}{10}+x=102\frac{1}{6}\\\\

x=102\tt\displaystyle\frac{1}{6}-100\frac{3}{10}\\\\

x=102\tt\displaystyle\frac{5}{30}-100\frac{9}{30}\\\\

x=101\tt\displaystyle\frac{35}{30}-100\frac{9}{30}\\\\

x=1\tt\displaystyle\frac{26}{30}\\\\

x=1\tt\displaystyle\frac{13}{15}
