160. Вычислите значение выражения |p| : |k|, если: 1) p = -4\frac{3}{4}, k = 7\frac{3}{5}; 2) p = 8,48, k = -0,08.

1) p = -4\frac{3}{4} = -\frac{19}{4}, k = 7\frac{3}{5} = \frac{38}{5} |p| : |k| = |-\frac{19}{4}| : |\frac{38}{5}| = \frac{19}{4} : \frac{38}{5} = \frac{19}{4} * \frac{5}{38} = \frac{1}{4} * \frac{5}{2} = \frac{5}{8} = 0.625 2) p = 8,48, k = -0,08 |p| : |k| = |8,48| : |-0,08| = 8,48 : 0,08 = 106
