Answer 1

\(0,3+\dfrac{-13}{2}+\dfrac{6}{5}\)

\(=\dfrac{3}{10}+\dfrac{-13}{2}+\dfrac{6}{5}\)

\(=-5\)

Answer 2

0,3+\(\dfrac{-13}{2}+\dfrac{6}{5}\)

= \(\dfrac{3}{10}+\dfrac{-65}{10}+\dfrac{12}{10}\)

= \(\dfrac{-50}{10}\)=-5

Answer 3

\(0,3+\dfrac{-13}{2}+\dfrac{6}{5}=\dfrac{3}{10}+\dfrac{-13}{2}+\dfrac{6}{5}=\dfrac{-50}{10}=-5\)

Answer 4

\(0,3+\dfrac{-13}{2}+\dfrac{6}{5}\) \(=\dfrac{3}{10}+\dfrac{-13}{2}+\dfrac{6}{5}=-\dfrac{31}{5}+\dfrac{6}{5}=-5\)

Answer 5

\(0,3+\dfrac{-13}{2}+\dfrac{6}{5}=0,3-6,5+1,2=-5\)

Answer 7

\(0,3+\dfrac{-13}{2}+\dfrac{6}{5}\)

=\(\dfrac{3}{100}+\dfrac{-13}{2}+\dfrac{6}{5}\)

=\(\dfrac{3}{100}+\dfrac{-650}{100}+\dfrac{120}{100}\)

=\(\dfrac{3+\left(-650\right)+120}{100}\)

=\(\dfrac{-527}{100}\)
