1. Вычислить: 1) -3,7+ (-5,93) 2) 7,421 - 8,51 3) -4,76-(-5,92) 4) -4/7 + 3 5/14 5) 3/8 + (-5/12) 6) 3/4 : (-5/3) 7) -3/8 * 5/4 8) -0,5 * (-0,2) 9) 3,2 * (-0,3) 10) -4/15 * 5/24

1) $$-3,7 + (-5,93) = -3,7 - 5,93 = -9,63$$ 2) $$7,421 - 8,51 = -1,089$$ 3) $$-4,76 - (-5,92) = -4,76 + 5,92 = 1,16$$ 4) $$-\frac{4}{7} + 3\frac{5}{14} = - \frac{8}{14} + \frac{47}{14} = \frac{39}{14} = 2\frac{11}{14}$$ 5) $$\frac{3}{8} + (-\frac{5}{12}) = \frac{3}{8} - \frac{5}{12} = \frac{9}{24} - \frac{10}{24} = -\frac{1}{24}$$ 6) $$\frac{3}{4} : (-\frac{5}{3}) = \frac{3}{4} * (-\frac{3}{5}) = -\frac{9}{20}$$ 7) $$-\frac{3}{8} * \frac{5}{4} = -\frac{15}{32}$$ 8) $$-0,5 * (-0,2) = 0,1$$ 9) $$3,2 * (-0,3) = -0,96$$ 10) $$-\frac{4}{15} * \frac{5}{24} = -\frac{1}{3} * \frac{1}{6} = -\frac{1}{18}$$
