1. \frac{1}{3} \cdot (-9) = -3 2. \frac{2}{4} \cdot \frac{1}{6} = \frac{1}{12} 3. (-5) \cdot (-3,1) = 4. 15: (-0,5) = 5. 16 \cdot (-4) =

Ответ: смотри решение

1. \(\frac{1}{3} \cdot (-9) = \frac{1 \cdot (-9)}{3} = \frac{-9}{3} = -3\)
2. \(\frac{2}{4} \cdot \frac{1}{6} = \frac{2 \cdot 1}{4 \cdot 6} = \frac{2}{24} = \frac{1}{12}\)
3. \((-5) \cdot (-3,1) = 15,5\)
4. \(15 : (-0,5) = -30\)
5. \(16 \cdot (-4) = -64\)

Ответ: 1) -3; 2) 1/12; 3) 15,5; 4) -30; 5) -64
