Answer 1

\(\left(\dfrac{6}{5}-2,4\right):\dfrac{-3}{5}-\dfrac{3}{2}.\left(1\dfrac{1}{2}:\dfrac{1}{2}\right)\)

= \(\dfrac{-6}{5}\): \(\dfrac{-3}{5}-\dfrac{3}{2}.\left(\dfrac{3}{2}:\dfrac{1}{2}\right)\)

= \(\dfrac{-5}{2}\)

Answer 2

\(\left(\dfrac{6}{5}-2,4\right):\left(-3,5\right)-\dfrac{3}{2}.\left(1\dfrac{1}{2}:\dfrac{1}{2}\right)=-\dfrac{6}{5}:\left(-\dfrac{7}{2}\right)-\dfrac{3}{2}.3=\dfrac{12}{35}-3=-\dfrac{93}{35}\)

Answer 3

\(\left(\dfrac{6}{5}-2,4\right):\dfrac{-3}{5}-\dfrac{3}{2}.\left(1\dfrac{1}{2}:\dfrac{1}{2}\right)\) 

=\(\left(\dfrac{6}{5}-\dfrac{12}{5}\right):\dfrac{-3}{5}-\dfrac{3}{2}.\left(\dfrac{3}{2}:\dfrac{1}{2}\right)\) 

=\(\dfrac{-6}{5}:\dfrac{-3}{5}-\dfrac{3}{2}.3\) 

=\(2-\dfrac{9}{2}\) 

=\(\dfrac{-5}{2}\)
