Question

Answer 1

\(1,\dfrac{-3}{17}+\left(\dfrac{2}{3}+\dfrac{3}{17}\right)=\dfrac{-3}{17}+\dfrac{3}{17}+\dfrac{2}{3}=\dfrac{2}{3}.\\2,\dfrac{2}{3} +\left(\dfrac{5}{7}+\dfrac{-2}{3}\right)=\dfrac{2}{3}+\dfrac{-2}{3}+\dfrac{5}{7}=\dfrac{5}{7}.\\ 3,\dfrac{-37}{24}-\left(-\dfrac{13}{24}+\dfrac{1}{16}\right)=\dfrac{-37}{24}+\dfrac{13}{24}+\dfrac{1}{16}=-1+\dfrac{1}{16}=-\dfrac{15}{16}.\)

\(4,-\dfrac{2}{5}-\left(\dfrac{3}{11}+\dfrac{-2}{5}\right)=-\dfrac{2}{5}-\dfrac{3}{11}+\dfrac{2}{5}=-\dfrac{3}{11}.\)
