Me ajudem não consigo fazer

Answer 1

$\frac{3}{5}.( \frac{1}{2} - \frac{1}{3} )- \sqrt{ \frac{1}{100} } : \frac{1}{10} = \\ \\ = \frac{3}{5} .( \frac{1.3-1.2}{6} )- \frac{ \sqrt{1} }{ \sqrt{100} } : \frac{1}{10} = \\ \\ = \frac{3}{5}.( \frac{3-2}{6} )- \frac{1}{10} . \frac{10}{1} = \\ \\ = \frac{3}{5}.\frac{1}{6} -1= \\ \\ = \frac{3}{30} -1= \frac{1}{10} -1= \frac{1.1-1.10}{10} = \frac{1-10}{10} =- \frac{9}{10}$
