Решим данные математические выражения:
- $$|-5.2| + |3.6| = 5.2 + 3.6 = 8.8$$
- $$|-4.32| : |-1.8| = 4.32 : 1.8 = 2.4$$
- $$|-3\frac{5}{9}| - |-1\frac{11}{18}| = 3\frac{5}{9} - 1\frac{11}{18} = \frac{32}{9} - \frac{29}{18} = \frac{64}{18} - \frac{29}{18} = \frac{35}{18} = 1\frac{17}{18}$$
Выражения с переменными:
- $$-4.6 \cdot x \cdot 4.1 = -18.86x$$
- $$- \frac{5}{8}x - \frac{7}{9} = -\frac{45x}{72} - \frac{56}{72} = -\frac{45x + 56}{72}$$
- $$-3 \cdot x \cdot -3.2 = 9.6x$$
- $$- \frac{3}{8} \cdot x \cdot 0 = 0$$
