Question

`A=-2/3-((-5)/(-2)+(-5)/2).-5/8`

Answer 1

`A=-2/3-( (-5)/(-2) + (-5)/2 )* (-5/8)`

`A= -2/3 - (5/2 + (-5)/2 ) * (-5/8)`

`A= -2/3 - 0 * (-5/8)`

`A=-2/3`

Answer 2

\(A=-\dfrac{2}{3}-\left(\dfrac{-5}{-2}+\dfrac{-5}{2}\right).-\dfrac{5}{8}\\ =-\dfrac{2}{3}-\left(\dfrac{5}{2}-\dfrac{5}{2}\right).-\dfrac{5}{8}\\ =-\dfrac{2}{3}-0.-\dfrac{5}{8}\\ =-\dfrac{2}{3}-0\\ =-\dfrac{2}{3}\)

Answer 3

\(A=-\dfrac{2}{3}-\left(\dfrac{-5}{-2}+-\dfrac{5}{2}\right)\cdot-\dfrac{5}{8}\)
\(=-\dfrac{2}{3}-\left(\dfrac{5}{2}-\dfrac{5}{2}\right)\cdot-\dfrac{5}{8}\)
\(=-\dfrac{2}{3}-0\cdot-\dfrac{5}{8}\)
\(=-\dfrac{2}{3}-0=-\dfrac{2}{3}\)
