152. Вычислить значение выражения |x| : |у, если: 1) x=-3 2/5, y = 4 2/5; 2) x = 7,14, y = - 0,07.

1. $$x = -3\frac{2}{5} = -\frac{17}{5}, y = 4\frac{2}{5} = \frac{22}{5}$$ $$|x| = |-\frac{17}{5}| = \frac{17}{5}, |y| = |\frac{22}{5}| = \frac{22}{5}$$ $$|x| : |y| = \frac{17}{5} : \frac{22}{5} = \frac{17}{5} \cdot \frac{5}{22} = \frac{17}{22}$$

2. |x| = |7,14| = 7,14, |y| = |-0,07| = 0,07 |x| : |y| = 7,14 : 0,07 = 714 : 7 = 102

Ответ: 1) 17/22; 2) 102
