1) \(12 \cdot \left( \frac{1}{3} \right)^2 + \frac{2}{3}\)
2) \(18 \cdot \left( \frac{1}{2} \right)^2 + \frac{5}{2}\)
3) \(15 \cdot \left( -\frac{2}{3} \right)^2 - \frac{7}{3}\)
4) \(\left( \frac{1}{3} \right)^2 \cdot 3 - \frac{2}{9} \cdot \frac{2}{3}\)
5) \(\left( \frac{1}{3} \right)^3 \cdot \frac{9}{4} - \left( -\frac{1}{2} \right)^2\)
6) \(\left( -\frac{3}{2} \right)^2 - \frac{1}{2} \cdot 6\)
7) \(3 : \left( -\frac{3}{2} \right)^2 + \frac{1}{9} \cdot 6^1\)
