3. Вычислите: (0,008 + 0,992) : (5 · 0,6 − 1,4); 13,5 · 9,1 · (−3,3) : (−0,00013); (8 7/12 − 2 17/36) · 2,7 − 4 1/3 : 0,65; (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) \(13,5\cdot9,1\cdot(-3,3):(-0,00013)=(-405,405):(-0,00013)=3\,118\,500\).

3) \((8\frac{7}{12}-2\frac{17}{36})\cdot2,7-4\frac{1}{3}:0,65\)

\(=\left(\frac{307}{36}-\frac{89}{36}\right)\cdot\frac{27}{10}-\frac{13}{3}:\frac{13}{20}\)

\(=\frac{109}{18}\cdot\frac{27}{10}-\frac{20}{3}=\frac{327}{20}-\frac{20}{3}=\frac{581}{60}=9,683\overline{3}\).

4) \((1\frac{11}{24}+\frac{13}{36})\cdot1,44-\frac{8}{15}\cdot0,5625\)

\(=\left(\frac{35}{24}+\frac{13}{36}\right)\cdot\frac{36}{25}-\frac{8}{15}\cdot\frac{9}{16}\)

\(=\frac{131}{72}\cdot\frac{36}{25}-\frac{3}{10}=\frac{131}{50}-\frac{3}{10}=2,32\).

Ответ: 0,625; 3 118 500; \(\frac{581}{60}=9,683\overline{3}\); 2,32.
