Вопрос:

Вычислите: -41 + 16 * 3 29 - 4 * 19 15 - 12 * 6 $$(\frac{5}{6} - \frac{7}{18}) * \frac{3}{16}$$ $$2 - \frac{15}{28} : \frac{10}{21}$$ 9.3 - 11.4 : 1.5 (-2 + 0.625) * 8 77 : (3.8 - 8.2) (-2 + 0.625) * 8 (-2.4 + 9.9) : 12

Ответ:

-41 + 16 * 3 = -41 + 48 = 7 29 - 4 * 19 = 29 - 76 = -47 15 - 12 * 6 = 15 - 72 = -57 $$(\frac{5}{6} - \frac{7}{18}) * \frac{3}{16} = (\frac{15}{18} - \frac{7}{18}) * \frac{3}{16} = \frac{8}{18} * \frac{3}{16} = \frac{4}{9} * \frac{3}{16} = \frac{1}{3} * \frac{1}{4} = \frac{1}{12} $$2 - \frac{15}{28} : \frac{10}{21} = 2 - \frac{15}{28} * \frac{21}{10} = 2 - \frac{3}{4} * \frac{3}{2} = 2 - \frac{9}{8} = \frac{16}{8} - \frac{9}{8} = \frac{7}{8} 9.3 - 11.4 : 1.5 = 9.3 - 7.6 = 1.7 (-2 + 0.625) * 8 = (-1.375) * 8 = -11 77 : (3.8 - 8.2) = 77 : (-4.4) = -17.5 (-2 + 0.625) * 8 = (-1.375) * 8 = -11 (-2.4 + 9.9) : 12 = 7.5 : 12 = 0.625
