Решение:
a) \(1.6 - (-4.5) = 1.6 + 4.5 = 6.1\)
б) \(-135.2 : (-6.5) = 20.8\)
в) \(-1 \frac{7}{8} \cdot 1 \frac{1}{3} = -\frac{15}{8} \cdot \frac{4}{3} = -\frac{60}{24} = -\frac{5}{2} = -2.5\)
г) \(1 \frac{2}{3} : (-3 \frac{1}{3}) = \frac{5}{3} : (-\frac{10}{3}) = \frac{5}{3} \cdot (-\frac{3}{10}) = -\frac{15}{30} = -\frac{1}{2} = -0.5\)
