Ответ:

  1. \((0,008+0,992):(5\cdot0,6-1,4)=1:1,6=0,625\).
  2. \(3,5\cdot9,1\cdot(-3,3):(-0,00013)=808500\).
  3. \((8\frac7{12}-2\frac{17}{36})\cdot2,7-4\frac13:0,65=\frac{55}{9}\cdot\frac{27}{10}-\frac{13}{3}:\frac{13}{20}=\frac{33}{2}-\frac{20}{3}=\frac{59}{6}\).
  4. \((1\frac{11}{24}+\frac{13}{36})\cdot1,44-\frac8{15}\cdot0,5625=\frac{133}{72}\cdot\frac{36}{25}-\frac8{15}\cdot\frac9{16}=2,66-0,3=2,36\).

Ответ: 1) 0,625; 2) 808500; 3) \(\frac{59}{6}\); 4) 2,36.
