Answer 1

$1. \frac{9}{7} - \frac{8}{9}= \frac{81-56}{63}= \frac{25}{63} \\ 2. \frac{15}{18} -\frac{6}{12}= \frac{5}{6}- \frac{1}{2} = \frac{10-6}{12} = \frac{4}{12}= \frac{1}{3} \\ 3. \frac{5}{6} - \frac{1}{9} = \frac{45-6}{54} = \frac{39}{54}= \frac{13}{18} \\ 4. \frac{7}{8} - \frac{7}{10} = \frac{70-56}{80} = \frac{14}{80}= \frac{7}{40} \\ 5. 3 \frac{4}{7} -2 \frac{3}{5}= \frac{25}{7} - \frac{13}{5}= \frac{125-91}{35} = \frac{34}{35}$$\\ 6.2 \frac{3}{10} -1 \frac{4}{15}= \frac{23}{10} - \frac{19}{15} = \frac{345-190}{150} = \frac{155}{150} = \frac{31}{30} \\ 7. \frac{5}{8}- \frac{9}{16} = \frac{80-72}{128} = \frac{12}{128} = \frac{3}{32} \\ 8. \frac{19}{20} - \frac{3}{10} = \frac{190-60}{200} = \frac{130}{200} = \frac{13}{20} \\ 9.3 \frac{4}{9} -2 \frac{5}{8} = \frac{31}{9} - \frac{21}{8} = \frac{248-189}{72} = \frac{59}{72}$ \\ $10.9 \frac{2}{3} -5 \frac{1}{6} - 2\frac{8}{15}= \frac{29}{3}- \frac{31}{6}- \frac{38}{15}= \frac{59}{30}$
