3. Вычислите: 1) (0,008 + 0,992) : (5 · 0,6 − 1,4); 2) 13,5 · 9,1 · (−8,3) : (−0,00018); 3) (8 7/12 − 2 17/36) · 2,7 − 4 1/3 : 0,65; 4) (1 11/24 + 13/36) · 1,14 − 8/15 · 0,5625.

1. \((0.008+0.992):(5\cdot0.6-1.4)=1:(3-1.4)=1:1.6=0.625\).
2. \(13.5\cdot9.1\cdot(-8.3):(-0.00018)=1027.35\cdot8.3:0.00018=8527.005:0.00018=47372250\).
3. \(8\frac{7}{12}=\frac{307}{36}\), поэтому \(8\frac{7}{12}-2\frac{17}{36}=\frac{307-89}{36}=\frac{218}{36}=\frac{109}{18}\).
   \(\frac{109}{18}\cdot2.7-4\frac13:0.65=\frac{109}{18}\cdot\frac{27}{10}-\frac{13}{3}:\frac{13}{20}=\frac{327}{20}-\frac{20}{3}=\frac{581}{60}=9\frac{41}{60}\).
4. \(1\frac{11}{24}+\frac{13}{36}=\frac{35}{24}+\frac{13}{36}=\frac{131}{72}\).
   \(\frac{131}{72}\cdot1.14-\frac{8}{15}\cdot0.5625=\frac{131}{72}\cdot\frac{57}{50}-\frac{8}{15}\cdot\frac{9}{16}=\frac{2489}{1200}-\frac{3}{10}=\frac{2129}{1200}=1\frac{929}{1200}\).

Ответ: 1) 0,625; 2) 47 372 250; 3) 9 41/60; 4) 1 929/1200.
