\(a,=\dfrac{5}{8}+\dfrac{6}{11}-\dfrac{5}{8}=\dfrac{6}{11}\\ b,=\dfrac{3}{7}\left(26\dfrac{1}{3}-19\dfrac{1}{3}\right)-\dfrac{2}{5}=\dfrac{3}{7}\cdot7-\dfrac{2}{5}=3-\dfrac{2}{5}=\dfrac{13}{5}\\ c,=7,2+2,8-3,7-0,3=10-4=6\\ d,=\left(\dfrac{3}{2}-\dfrac{1}{2}\right)\cdot\dfrac{1}{9}+\dfrac{1}{6}=\dfrac{1}{9}+\dfrac{1}{6}=\dfrac{5}{18}\)
