Ответ:
- \(9\frac34+3\frac16=12+\frac{9}{12}+\frac2{12}=12\frac{11}{12}\).
- \(7\frac89-2\frac23=5+\frac89-\frac69=5\frac29\).
- \(11\frac7{12}+6\frac{11}{18}=17+\frac{21}{36}+\frac{22}{36}=18\frac7{36}\).
- \(5\frac59-2\frac47=3+\frac{35}{63}-\frac{36}{63}=2\frac{62}{63}\).
- \(9-2\frac37=6\frac47\).
- \(7\frac5{16}+4\frac16+3\frac38=14+\frac{15}{48}+\frac8{48}+\frac{18}{48}=14\frac{41}{48}\).
- \(8\frac59+7\frac34+12\frac7{12}=27+\frac{20}{36}+\frac{27}{36}+\frac{21}{36}=28\frac{17}{36}\).
- \(6\frac78-3\frac13+5\frac5{16}=8+\frac{42}{48}-\frac{16}{48}+\frac{15}{48}=8\frac{41}{48}\).
- \(5\frac8{15}+4\frac7{12}-3\frac{19}{20}=6+\frac{32}{60}+\frac{35}{60}-\frac{57}{60}=6\frac16\).
- \(5\frac9{14}-2\frac37+6.7=9+\frac9{14}-\frac6{14}+6.7-6.7=9\frac3{14}+6.7=15\frac{13}{35}\).
Ответ: 1) \(12\frac{11}{12}\); 2) \(5\frac29\); 3) \(18\frac7{36}\); 4) \(2\frac{62}{63}\); 5) \(6\frac47\); 6) \(14\frac{41}{48}\); 7) \(28\frac{17}{36}\); 8) \(8\frac{41}{48}\); 9) \(6\frac16\); 10) \(15\frac{13}{35}\).
