Verified answer

Resposta:

A resposta é [tex]=\frac{7}{24}\:ou\:0.2916[/tex]

Explicação passo a passo:

[tex]\left(\frac{-5}{12}\right)\left(\frac{-7}{10}\right)\\ \\ =\frac{-5}{12}\cdot \frac{-7}{10}\\ \\ =-\frac{5}{12}\left(-\frac{7}{10}\right)\\ \\ =\frac{5}{12}\cdot \frac{7}{10}\\ \\ =\frac{5\cdot \:7}{12\cdot \:5\cdot \:2}\\ \\ =\frac{7}{12\cdot \:2}\\ \\=\frac{7}{24}\:ou\:0.2916[/tex]

Bons estudos!

[tex]( - \frac{5}{12} ) \: . \: ( - \frac{7}{10} ) \\ \frac{5}{12} \: . \: \frac{7}{10} \\ \frac{1}{12} \: . \: \frac{7}{2} \\ \frac{1 \: . \: 7}{12 \: . \: 2} \\ \boxed{\boxed{\boxed{ \frac{7}{24} }}} \\ [/tex]
