a.) \(\frac{7}{20} \cdot 2.7 + 2.7 \cdot 1.35 + (0.4 \cdot \frac{1}{2}) - (4.2 - 1) \cdot \frac{3}{40}\)
b.) \(\left[ (6^{\frac{3}{5}} - 3^{\frac{3}{14}}) \cdot 5^{\frac{5}{6}} \right] : \left[(21 - 1.25) \cdot 2.5\right]\)
c.)
\(0.125 - \frac{1}{5} + \frac{1}{7} + \frac{1}{2} + \frac{1}{3} = 0.2\)
\(0.375 - \frac{3}{5} - \frac{3}{4} + 0.5 = \frac{3}{10}\)
