Question

(5/2 -3):(1 1/2 - 2/3) rápido por favor ​

Answer 1

$( \frac{ 5 }{ 2 } -3) \div (1 \frac{ 1 }{ 2 } - \frac{ 2 }{ 3 } ) \\ \\ \frac{\frac{5}{2}-\frac{6}{2}}{\frac{1\times 2+1}{2}-\frac{2}{3}} \\ \\ \frac{\frac{5-6}{2}}{\frac{1\times 2+1}{2}-\frac{2}{3}} \\ \\ \frac{-\frac{1}{2}}{\frac{1\times 2+1}{2}-\frac{2}{3}} \\ \\ \frac{-\frac{1}{2}}{\frac{2+1}{2}-\frac{2}{3}} \\ \\ \frac{-\frac{1}{2}}{\frac{3}{2}-\frac{2}{3}} \\ \\ \frac{-\frac{1}{2}}{\frac{9}{6}-\frac{4}{6}} \\ \\ \frac{-\frac{1}{2}}{\frac{9-4}{6}} \\ \\ \frac{-\frac{1}{2}}{\frac{5}{6}} \\ \\ -\frac{1}{2}\times \left(\frac{6}{5}\right) \\ \\ \frac{-6}{2\times 5} \\ \\ \frac{-6}{10} \\ \\ -\frac{3}{5} = - 0.6$

Espero ter ajudado!!
