Вычислите: 1) (0,008 + 0,992) : (5 · 0,6 − 1,4); 2) 13,5 · 9,1 · (−3,3) : (−0,00013); 3) (8 7/12 − 2 17/36) · 2,7 − 4 1/3 : 0,65; 4) (1 11/24 + 13/36) · 1,44 − 8/15 · 0,5625.

1. \((0.008+0.992):(5\cdot0.6-1.4)=1:(3-1.4)=1:1.6=0.625\).

2. \(13.5\cdot9.1\cdot(-3.3):(-0.00013)=405.405:0.00013=3118500\).

3. \(8\frac{7}{12}-2\frac{17}{36}=6\frac{1}{9}=\frac{55}{9}\).

   \(\frac{55}{9}\cdot2.7=\frac{55}{9}\cdot\frac{27}{10}=\frac{33}{2}\).

   \(4\frac{1}{3}:0.65=\frac{13}{3}:\frac{13}{20}=\frac{20}{3}\).

   \(\frac{33}{2}-\frac{20}{3}=\frac{59}{6}=9\frac{5}{6}\).

4. \(1\frac{11}{24}+\frac{13}{36}=\frac{35}{24}+\frac{13}{36}=\frac{131}{72}\).

   \(\frac{131}{72}\cdot1.44=\frac{131}{72}\cdot\frac{36}{25}=\frac{131}{50}\).

   \(\frac{8}{15}\cdot0.5625=\frac{8}{15}\cdot\frac{9}{16}=\frac{3}{10}\).

   \(\frac{131}{50}-\frac{3}{10}=\frac{116}{50}=\frac{58}{25}=2.32\).

Ответ: 1) 0,625; 2) 3 118 500; 3) 9 5/6; 4) 2,32.
