Answer 1

$\it \dfrac{1}{2}:\left( \dfrac{^{2)}1}{5} -\dfrac{1}{10}\right)\cdot2 \dfrac{1}{3}\cdot \dfrac{3}{14} = \dfrac{1}{2}: \dfrac{1}{10}\cdot \dfrac{7}{3}\cdot \dfrac{3}{14} = \dfrac{1}{2}\cdot \dfrac{10}{1}\cdot \dfrac{7}{3}\cdot \dfrac{3}{14} = \dfrac{5}{2}$

Answer 2

$\it \dfrac{1}{2} \div ( \dfrac{1}{5}^{ \cdot2} - \dfrac{1}{10}) \cdot 2 \dfrac{1}{3} \cdot \dfrac{3}{14} = \\ \\ \\ \\ \it \: \dfrac{1}{2} \div ( \dfrac{2}{10} - \dfrac{1}{10} ) \cdot \dfrac{7}{3} \cdot \dfrac{3}{14} = \\ \\ \\ \\ \it\frac{1}{2} \div \dfrac{1}{10} \cdot \dfrac{7}{3} \cdot \dfrac{3}{14} = \\ \\ \\ \\ \it\dfrac{1}{2} \cdot \dfrac{10}{1} \cdot \dfrac{7}{3} \cdot \dfrac{3}{14} = \dfrac{210}{84} ^{ \div 3} = \dfrac{70}{28}^{ \div 7} = \dfrac{10}{4} ^{ \div 2} = \dfrac{5}{2}$
