Question

d)(−0,75)−[(−2)+3/2]:1,5+(−5/4)
 

Answer 1

(−0,75)−[(−2)+3/2]:1,5+(−5/4)

= (-0,75) - (-1/2) : 1,5 + (-5/4)

= (-0,75) - (-1/3) + (-5/4)

= -5/3

Answer 2

\(d,\left(-0,75\right)-\left[\left(-2\right)+\dfrac{3}{2}\right]:1,5+\left(\dfrac{-5}{4}\right)=\left(-0,75\right)-\left(\dfrac{-1}{2}\right):\dfrac{3}{2}+\left(\dfrac{-5}{4}\right)=\left(\dfrac{-3}{4}\right)-\dfrac{-1}{3}+\left(\dfrac{-5}{4}\right)=-\left[\left(\dfrac{-3}{4}\right)+\left(\dfrac{-5}{4}\right)\right]-\dfrac{-1}{3}=\left(-2\right)+\dfrac{1}{3}=\dfrac{-5}{3}\)
