`-3/5 - (-19/24)+ -7/24`
`=-3/5+19/24+ -7/24`
`=-3/5+ (19/24 + - 7/24)`
`=-3/5+ 1/2`
`=-1/10`
\(-\dfrac{3}{5}+\dfrac{19}{24}-\dfrac{7}{24}=\) \(-\dfrac{3}{5}+\dfrac{12}{24}=\) \(-\dfrac{3}{5}+\dfrac{1}{2}\) \(=\dfrac{-6+5}{10}=-\dfrac{1}{10}\)
−35−(−1924)+−724-35-(-1924)+-724
=−35+1924+−724=-35+1924+-724
=−35+(1924+−724)=-35+(1924+-724)
=−35+12=-35+12
=−110
\(\dfrac{-3}{5}-\left(\dfrac{-19}{24}\right)+\dfrac{-7}{24}\\ =\dfrac{-3}{5}+\dfrac{19}{24}+\dfrac{-7}{24}\\ =\dfrac{-3}{5}+\left(\dfrac{19}{24}+\dfrac{-7}{24}\right)\\ =\dfrac{-3}{5}+\dfrac{1}{2}\\ =\dfrac{-6}{10}+\dfrac{5}{10}\\ =\dfrac{-1}{10}\)
