​

Answer 1

$0.5 {}^{3} \div 0.5 {}^{2} \times ( \frac{3}{5} ) = \\ = (\frac{5}{10}) {}^{3} \div ( \frac{5}{10}) {}^{2} \times ( \frac{3}{5}) = \\ = ( \frac{1}{5}) {}^{3} \div ( \frac{1}{5} ) {}^{2} \times ( \frac{3}{5} ) = \\ = \frac{1}{125} \div \frac{1}{25} \times ( \frac{3}{5} ) = \\ = \frac{1}{125} \times \frac{25}{1} \times ( \frac{3}{5} ) = \\ = \frac{1}{5} \times \frac{3}{5} = \\ \frac{3}{25}$
