-5/4-(-1/2)2 Sobre (2/3)-¹

Answer 1

$\dfrac{- \dfrac{5}{4} -\left(-\dfrac{1}{2} \right)^2 }{ \dfrac{2}{3}^{-1} } \to~~~~ \dfrac{- \dfrac{5}{4} -\left(\dfrac{1}{4} \right) }{ \dfrac{3}{2}^1 } \to~~~~ \dfrac{- \dfrac{5}{4} -\dfrac{1}{4} }{ \dfrac{3}{2} } \to~~~~\\\\\\\\ \dfrac{\dfrac{-5-1}{4} }{ \dfrac{3}{2} } \to~~~~ \dfrac{\dfrac{-6}{4} }{ \dfrac{3}{2} } \to~~~~ \dfrac{-6}{4} \times \dfrac{2}{3}\to~~~~ \dfrac{-12}{12}\to~~~~ \large\boxed{~-1~}$

Answer 2

$\frac{- \frac{5}{4} - (- \frac{1}{2})^{2} }{ \frac{2}{3}^{-1} }$

$\frac{- \frac{5}{4} - \frac{1}{4}}{ \frac{2}{3}^{-1} }$

$\frac{- \frac{6}{4}}{ \frac{2}{3}^{-1} }$

${- \frac{6}{4}. \frac{2}{3} }$

= -1
