Question

\(-\dfrac{3}{2}-\dfrac{-7}{5}\)

Answer 1

\(-\dfrac{3}{2}-\dfrac{-7}{5}=\dfrac{-3.5}{2.5}-\dfrac{-7.2}{5.2}=-\dfrac{15}{10}-\dfrac{-14}{10}=\dfrac{-15-\left(-14\right)}{10}=-\dfrac{1}{10}\)

Answer 2

\(-\dfrac{3}{2}-\dfrac{-7}{5}\\ =-\dfrac{3}{2}+\dfrac{7}{5}\\ =\dfrac{-15}{10}+\dfrac{14}{10}\\ =-\dfrac{1}{10}\)

Answer 3

\(=-\left(\dfrac{3}{2}-\dfrac{7}{5}\right)=-\left(\dfrac{1}{10}\right)=-\dfrac{1}{10}\)
