$196)\; \; 9+\frac{3}{17}= \frac{156}{17}=9\frac{3}{17}\\\\\frac{9}{72}+5= \frac{1}{8}+5=5\frac{1}{8}\\\\4\frac{5}{18}+2\frac{4}{18}=6\frac{9}{18}=6 \frac{1}{2}=6,5\\\\6\frac{7}{15}-2\frac{3}{15}=4\frac{4}{15}\\\\9\frac{11}{16}+4\frac{3}{16}-2\frac{2}{16}=11 \frac{12}{16}=11 \frac{3}{4}=11,75\\\\15\frac{7}{10}+2\frac{2}{10}-4\frac{1}{10}=13 \frac{8}{10}=13\frac{4}{5}=13,8$

$198)\; \; a)\; \; x+8 \frac{4}{29}=12\\\\x=12-8\frac{4}{29}\\\\x=4-\frac{4}{29}\\\\x=3\frac{25}{29}\\\\b)\; \; 5 \frac{7}{18}-(x-2\frac{5}{18})=1\frac{1}{18}\\\\x-2\frac{5}{18}=5\frac{7}{18}-1\frac{1}{18}\\\\x-2\frac{5}{18}=4\frac{6}{18}\\\\x=4\frac{6}{18}+2\frac{5}{18}\\\\x=6\frac{11}{18}$

$199)\; \; 1-(\frac{4}{11}+\frac{5}{11})=1-\frac{9}{11} =\frac{11}{11}-\frac{9}{11}=\frac{2}{11}$
