a) 11/24 - 5/41 + 13/24 +0,5 - 36/41

=( 11/24 + 13/24) -( 5/41 - 36/41) +0,5 

= 1 - 1 + 0,5 

= 0,5

b) 1/2 * 3/4 + 1/2 * 1/4 + 1/2 

1/2 * ( 3/4 + 1/4 ) + 1/2

= 1/2 * 1 + 1/2 

= 1

c) ( -3/4 )^2 : ( -1/4 ) ^2 + 9 *  ( -1/9 ) + ( -3 /2 ) 

= 9/16 : 1/16 + 9 * ( -1/9) + ( -3/2) 

= 9 + (-1) + (-3/2) 

= 13/2 

d) \(\sqrt{0,25}\cdot\left(-3\right)^3-\sqrt{\dfrac{1}{81}}:\left(\dfrac{-1}{3}\right)^3\)

= \(\dfrac{1}{2}\cdot\left(-27\right)-\dfrac{1}{9}:\dfrac{1}{9}\)

\(\dfrac{ }{-27}\)
