Question

4 1/2 : ( 2,5 - 3 3/4 ) + -1/2^2

Answer 1

   \(4\frac{1}{2}:\left(2,5-\frac{33}{4}\right)+\left(-\frac{1}{2}\right)^2\)

= \(\frac{9}{2}:\left(-\frac{23}{4}\right)+\frac{1}{4}\)

= \(-\frac{18}{23}+\frac{1}{4}\)

= \(-\frac{49}{92}\)

Answer 2

   4 1/2 : ( 2,5 - 3 3/4 ) + -1/2^2

= 4 1/2 : ( 2,5 - 15/4 ) + - 1/2

= 9/2 : -5/4 + -1/2

= -18/5 + -1/2

= -41/10 

= - 4,1.
