9. Вычислите значение выражения |x|/|y|, если: 1) x = -3\frac{2}{3}, y = 4\frac{2}{5}; 2) x = 7,14, y = -0,07.

1) \(x = -3\frac{2}{3} = -\frac{11}{3}\), \(y = 4\frac{2}{5} = \frac{22}{5}\). \(|x| = |-\frac{11}{3}| = \frac{11}{3}\), \(|y| = |\frac{22}{5}| = \frac{22}{5}\). \(\frac{|x|}{|y|} = \frac{\frac{11}{3}}{\frac{22}{5}} = \frac{11}{3} \cdot \frac{5}{22} = \frac{1 \cdot 5}{3 \cdot 2} = \frac{5}{6}\). 2) \(x = 7,14\), \(y = -0,07\). \(|x| = |7,14| = 7,14\), \(|y| = |-0,07| = 0,07\). \(\frac{|x|}{|y|} = \frac{7,14}{0,07} = 102\).
