4. Вычислите: 1) |-5,71| + |-2,51| – 14,32; 2) $$\frac{5}{42} : 1 - 1\frac{1}{3}$$.

1) |-5,71| + |-2,51| – 14,32 = 5,71 + 2,51 - 14,32 = 8,22 - 14,32 = -6,1. 2) $$\frac{5}{42} : 1 - 1\frac{1}{3} = \frac{5}{42} : (\frac{3}{3} - \frac{4}{3}) = \frac{5}{42} : (-\frac{1}{3}) = \frac{5}{42} * (-3) = -\frac{5 * 3}{42} = -\frac{5}{14}$$. Ответ: $$-\frac{5}{14}$$
