Ответ:

  1. \(8+\frac{15}{22}=8\frac{15}{22}\).
  2. \(\frac{11}{35}+2=2\frac{11}{35}\).
  3. \(5\frac{7}{24}+7\frac{5}{24}=12\frac{12}{24}=12\frac12\).
  4. \(12\frac67-5\frac87=12\frac67-6\frac17=6\frac57\).
  5. \(10\frac{16}{26}-6\frac{10}{27}+4\frac5{27}=10\frac8{13}-6\frac{10}{27}+4\frac5{27}=4\frac8{13}-\frac5{27}=4\frac{151}{351}\).
  6. \(15\frac8{10}-9\frac7{10}+8\frac2{10}=15\frac8{10}-9\frac7{10}+8\frac2{10}=14\frac3{10}\).

Ответ: 1) \(8\frac{15}{22}\); 2) \(2\frac{11}{35}\); 3) \(12\frac12\); 4) \(6\frac57\); 5) \(4\frac{151}{351}\); 6) \(14\frac3{10}\).
